If you have regular periods and are looking to understand the signs and symptoms of your cycle and what constitutes as healthy and not, i think this is a great book. If you've got PCOS / endometriosis and are hoping for a deeper dive into what you might be experiencing and why, ways to alleviate your symptoms and how to help regulate your cycle, this isn't for you.


I've been waiting for months for this book having followed Hazel for years and knowing she has PCOS, I was expecting much more focus on PCOS beyond the generic advice given by doctors and found myself disappointed at how surface level it was. I recognise there's only so much you can put in writing based on personal experience, especially when you hold the title of doctor, as some may not get the same results as yourself, but honestly researching via google and podcasts has taught me more than this book covered.
Additionally found myself surprised at advice like taking a contraceptive pill if you find ovulation painful- isn't this part of the problem with PCOS and doctors only responding with "go on the pill and come back when you want kids"??

That said, i do think a book explaining periods is an amazing step in the right direction for women generally as this information isn't taught at school and i think younger me would have felt much more confident about dealing with my period and body image changes through working/ sports /holidays if l'd had this book and could understand why I felt different every day of the month.

Ahhhh. I really wanted to like this.

As someone who has done quite a lot of research myself into the topic of periods, PCOS and just being quite in tune with my body, this book was just too much 'going back to basics'. I don't feel like I've learned anything new personally... BUT at the same time, I would have loved to have access to this kind of book back when I was a teenager and just starting to get my period.

I think the author is doing an important job of raising awareness of menstrual cycles. It made me quite sad to read all the contradicting research examples. Some of the chapters, the author talks about different solutions and advice but then always ends on a note that there's not much evidence, so can't recommend any certain solution, just try all the things yourself and see what fits. And it's not a dig at the author - it just shows how much research is still needed on this topic and how overlooked it's been.

Dr Hazel raises a lot of important issues in the book. I might just be too informed on this topic already! And my expectations were to learn something from this. I also thought the author will cover PCOS more as someone who is diagnosed with it.

I would, however, recommend to a teenager who is just starting on her menstrual cycle journey. Or someone who never took much notice to their periods and wants to learn more!

I have read a few books surrounding this topic so I didn’t find out anything new, most of the information was pretty basic and I found that in the sections discussing the pill and its effects on the cycle there was no definitive answers or studies so I didn’t see the point in including it if there was nothing to elaborate on. Overall a good book for teenagers or people who don’t really know much about periods, but nothing groundbreaking in my honest opinion!

This was...basic.
I would say it's a decent book for a young woman who doesn't know much about menstruation.
However as someone who has suffered from endometriosis for 20 years, this was a book that lacked substance.
I thought endometriosis would have a bigger section considering 1 in 10 women have it. But it was just a tiny part of the appendix at the end.
In my opinion there are much better books out there for general information but also to look into the sections in more detail.
Overall, passed with have correct information but wasn't exactly crammed with it!

As a chap, my chapette suggested I read this one. I learned a lot and I'm already spotting the misinformation memes that the author talks about as her inspiration for writing this book.

So mission accomplished 4/5 👍

3/5 ⭐️ This was a helpful book to reassure me of my knowledge about my periods. It scratched the surface of many topics, and I do wish it contained a bit more detail, case studies and stats (unusual for me as usually I’d rather less!!). Howeverrrrr, I have convinced my boyfriend to read this so will see what he thinks!😼

We’re so behind as a society on our understanding of the menstrual cycle that this book still feels like a must-read for every teenager (both women and men!!). That said, all info in this book remain quite basic and shallow. It is very frustrating to read that research is still at its infancy on many many areas related to our cycles despite relating to half of humanity (!!!). Hence, it would have been interesting to cover less info (especially those with poor scientific background) and dig more into specific topics. That said, thanks to Dr Wallace for raising awareness!! Very VERY important topic.

Quite liked it. Gave a really good overview of everything. Bit sad it did not dive even more into things. But would recommend for the basic knowledge of the areas. Also nice it added boobs, hair and skin

Soooo informative and changed my perspective on so many things. Wish I learnt this kind of stuff in school!! So much more informed and neutral than the TikTok anti-birth control brigade. Here for it!!!!

I personally really loved this book!

As a girl who really struggles with multiple symptoms including:

- Very painful and heavy periods
- Low mood
- Cystic acne
+ many other conditions related to menstruation and female hormones

I found this book incredibly helpful, specifically the chapters around nutrition, and how the cycle actually works.

That said, I do agree with some peoples reviews in a sense that this may seem a little “beginner” to some. I personally didn’t find this, but that is coming from someone who doesn’t know much to begin with!

If you’re already pretty clued up in women’s cycles, hormones and menstruation, then this probably isn’t for you! However, If you’re like me and are trying to figure out what the HECK going on with your body, I’d highly recommend this 🫶🏼

Definitely my favourite of Hazel Wallace’s books. She’s one of the few influencers who’s also a doctor and still manages to keep everything genuinely real. I learned so much about periods from this, and it’s given me such a clearer understanding of my body… what’s changing, why it’s happening, and how to actually work with it. I feel more in tune, more prepared, and way better at communicating what I need!

It even helped me realise there are about seven days a month where I genuinely feel my best (lol, I’ll take it).
Absolutely here for more research and honest conversations about female health.

I would recommend this book for “starters”. Perfect for anyone wanting to understand the basics without feeling overwhelmed.

3 stars is generous I feel, and I give it a generous 3 only because I want to promote more books/research and conversation surround hormones and women’s health.

After recently being diagnosed with PMDD I wanted to find something in this book that would be helpful, but as the author said in nearly every chapter “research is limited”. Welcome, to the female world. I did find some points useful and highlighted any helpful tips and suggestions surrounding nutrition and supplements, as this is an area that I find overwhelming and heavily marketed.

Overall, I think I would have loved this book at 16 and I’d have found it very informative and helpful. At 29, I feel as though it was very low level and at points, generic.

A solid introductory book on the subject. I wanted more information, but the issue is the dearth of decent research rather than the author not covering it.
Women’s health has historically been a neglected field of of study, hopefully we are at a point now where we can significantly improve this - we need more research into menstruation and conditions like endometriosis, PMDD, and PCOS.

glad to read a book that's actually nuanced about evidence, felt like Period Power was way too much based on anecdotal experience than legit data, so this book by Dr Hazel Wallace is refreshing. Also love her recipes!

I was hoping for deeper insights into topics like endometriosis, and this was not it. Very generalist summary rather than in depth comparison of the evidence and tools

Useful for a broader knowledge of how hormones can affect women's health and specific conditions linked with this. Showed the need for more scientific research into these things as SO many things are under researched.
So much information that I don't quite know what to do with! But a lot of good stuff, to guide healthy living through the weeks of changing hormones.

If i had a penny for every time i read “The results of the studies about this are inconclusive and in some cases contradictory…”
I really liked the idea and intention of this book, but i think you can get this same information if you follow the author on her social media channels. Overall, I had higher expectations and expected to learn way more things.

Don’t get me wrong, I think any steps towards literacy on reproductive health and women’s health are incredibly important and I’m glad this book exists!

However, I’m definitely not the target audience for this. And I wonder if most people buying it are. All the topics lack depth and are discussed on a superficial level. If you’re the kind of person who goes out and buys this book, you probably already know all the basic information it covers.

Sadly I agree with some of the other reviews of this book, I really wanted to like it but feel it’s far too basic of a look on the topics of periods and women’s health. This is great for teenagers or anybody starting their research but not sure I agree with the statements on cover.

Es más bien un 2,5 ⭐, pero Hazel me cae muy bien así que no quiero bajarle la nota.

Vale, empecemos porque no es un mal libro. Pero siento que, leído un libro sobre este tema, leídos todos. Y, ademas, me lo esperaba bastante más detallado. Siento que le falta ahondar en muchos temas, aunque claro está que si lo hiciera en todos sería interminable. Decir tres párrafos del SOP y de la AH no me parece mucho, de todos modos.

Me gusta cómo está dividido, y una cosa que me ha gustado todavía más es que no intentan venderte humos de haz esto o haz lo otro, sino que, humildemente, explica que la evidencia no es concluyente. Podría ser que sí, podría ser que no. Así que el bottomline es que te escuches, te registres y veas qué funciona para ti. De momento es lo que hay hasta que haya más investigación. Fantasía lo de ser mujer eh.

Dicho esto, siento que habiendo tantas cosas "en duda", habría sido mejor hablar de las diferentes condiciones menstruales más a fondo. Porque, si has tenido alguna de ellas, es muy probable que ya te sepas lo que se dice en el libro, que es lo básico. No es un libro de profundizar, es pura divulgación. Y está bien. Hablar más del ciclo está bien. Hablar de la variedad y diversidad de problemas que podemos tener está muy bien. Pero no siento que haya cumplido con las promesas que promete el título.

Quizás lo recomendaría si quieres saber más sobre el ciclo y sabes bastante poco. Si no te lo repasas desde tercero de la eso y no te sabes que hay una fase folicular y otra lutea. Pero si tienes un mínimo de eso, quizás es mejor leerse otro. Yo lo voy a hacer

This book was not what I was expecting. It wasn't marketed correctly. If it had sad "an introduction to your period and what we know so far", I would have still probably read it, but wouldn't have expected as much from it. In a way, I wanted this book to be inspiring. I wanted it to tell me that I really can regain control of my period and hormones.

The author here would repeat the same type of structure in her writing, firstly, writing down some recommendations, then, encouraging you to figure it out yourself and thirdly, saying there is little evidence for such things.

I also got quite angry when it was recommended that one should go on the pill, and told multiple times, to speak to your healthcare provider. This book was meant to be more than what everyone else says. It was meant to tell me that we know little, try this, but there is hope.

I think a good book for introductions, and when you first start having a period, good to know. Other than that, I am so deeply disappointed- sorry Dr Hazel Wallace.

I think that every young woman should read this book. And no, its not because it solves every question you have ever had about your body. And no its not the most engaging sci-comm book I have ever read.

This book is very much what I would envision a 3h long conversation with my ideal GP (if I could get such an appointment). Simple, clear. Answering questions you have about a changing body with true to fact clinical research and personal experience as a clinician. Sometimes, that means that the GP will tell you what to do. Other times, they will tell you “we dont have enough data to make such a statement, but this is what you CAN do”. And gosh, isn’t that just refreshing. None of the stuff mentioned in the book was exactly new to me. But as a 27 years old woman I had to learn a lot of those lessons the hard way. I wish I had this when I just got my period - I was confused and scared and had no idea how to cope with a lot of the side effects that went with it.

Tai žmogaus anatomija 🫀, fiziologija 🧪, patologija 🧫bei medicininiais tyrimais 🧬 pagrįsta knyga, kuri padeda suprasti, jog moters menstruacinis ciklas yra tiesiogiai priklausomas nuo mitybos 🍎, fizinio aktyvumo 🏋️‍♀️, miego 🛌 ir streso lygio 🫨; ir kad pastarasis turi įtakos mitybos pasirinkimams, fiziniam aktyvumui, miegui, nuotaikai, libido, savęs vertinimui ir odos bei plaukų būklei. Taip pat, labiai išsamiai aiškinamas hormoninių kontraceptikų 💊 poveikis visiems šiems aspektams, o tai labai aktuali tema tarp moterų ‼️

Visi mūsų planetos 🌍 gyventojai turėtų perskaityti šią knygą (taip, visi, vyrai 🧑🏽‍🦱 ypač), kad suvoktume kaip ir kodėl veikia moters organizmas 👩🏽‍🦱; kad nustotume menstuacijų ciklą laikyti taboo tema 🫢; kad suprastume kiek mažai medicininių tyrimų, nukreiptų ties moters reprodukcine sistema, atliekama 🔬; kad pradėtume sveiką menstruacinį ciklą laikyti geros sveikatos rodikliu 🩸 ir dar daug kitų argumentų, kodėl privalu paimti šią knygą 📖 į rankas.

I can understand why some people are upset that this book doesn’t go into more detail about PCOS, especially as we know that Dr Hazel has PCOS herself. But I found this book before I knew who Dr Hazel Wallace was, so I came in with no expectations. I consider myself pretty clued up on the topic of women’s health and menstrual health, and yet I was still surprised by some of this information. I think this is a really important book for all women, especially young women. We need to reiterate the fact that one’s menstrual health is almost always linked to and reflective of their overall health, and this is a great start to educating people on that.

Unfortunately, this book just missed the mark for me. It felt like a very basic overview of the menstrual cycle rather than a deep dive. I appreciate that the research in this field is limited but that left it feeling like there wasn’t much to say or to learn. Perhaps would be better if read as a physical book rather than an audiobook and therefore could have used it as something to refer to. That being said, if you know very very little on the menstrual cycle, options for contraception and menstrual abnormalities this could be a good read :)

Great book! Good work Dr. Hazel Wallace!
I have been following her on Instagram for some time now. I really appreciate her work and her recipes.
I don't quite understand the low rating, though.
I know many of us have done our own research and are familiar with much of what is written in the book, but there are still millions of women who have no idea what is happening with their bodies—women who are dismissed by their doctors and told, “It’s all in your head.”

We need to advocate for ourselves, and we need well-researched books like this. There will never be enough of them.
