Pregnancy Interrupted: The Science and Stories of How Pregnancies Really End

by Kate Clancy

A compassionate, evidence-based look at pregnancy loss—how and why it happens, and why the assurances of the medical industry don’t reflect the reality

One of the most prevalent myths about human pregnancy is that of all possible outcomes, a baby is the most likely. Pregnancy Interrupted challenges the misleadingly linear narrative that begins with two lines on a pregnancy test and ends with a newborn. Drawing on Kate Clancy’s own deeply personal stories of pregnancy loss and moving interviews with others, it reveals how the frequency of loss and miscarriage is far more common than most realize. This provocative book makes an impassioned, fact-based case for truthfulness and care at a time when inaccurate images of fetuses abound, electronic impulses continue to pass for a heartbeat, and reproductive autonomy is criminalized.

Presenting the unvarnished science of pregnancy loss, Clancy validates the experiences of women and gender minorities, offers solace for the person on her third miscarriage, and gives guidance for lawmakers and advocates seeking change. While genetic errors make some losses inevitable, this is not the whole story. Clancy describes how other factors increase the risk—from the choices we sometimes make to environmental and social conditions that go overlooked or ignored. She exposes the links between miscarriage and stressors like physical and emotional violence and explores how we might prevent miscarriages and stillbirths while mitigating the trauma when they do occur.

Pregnancy Interrupted provides an eye-opening account of pregnancy and loss as an unpredictable yet universal experience.

This is a fantastic & compassionate book on pregnancy loss that should be required reading for anyone that is not too sensitive to the content. (Cis men, please read this book!!!)

Content Warnings: medical trauma, medical racism, domestic violence, graphic childbirth, pregnancy loss, still birth, racism, sexism, fatphobia, ableism, etc.

Overall this book was a fantastic mix of both personal narrative and narratives of other women who dealt with pregnancy loss. I thought Kate Clancy did an excellent job as a biological anthropologist weaving in biology, sociology, politics, etc.

I was not expecting this book to cover domestic violence and also incarcerated pregnant folks, but I really appreciated those chapters.

I learned A LOT about the science of pregnancy and pregnancy detection. One example: pregnancy tests are detecting a chemical (HCG) that is released by the embryo when the embryo starts to interface with the uterus, so really the test is a detection of the formation of placenta and not necessarily a viable pregnancy.

Clancy interviewed many women and shared their experiences with pregnancy and pregnancy loss in this book, which really enhanced the book. One story that will stick with me is (now passed) geneticist Adriana Romero-Olivares's experience with genetic testing while pregnant with her son. The genetic testing indicated that her son had a 50% chance of having Fragile X. But since she is a scientist, she asked to see the raw data, once she reviewed it she saw that her son's risk was much MUCH lower and decided to keep her pregnancy going. An example that genetic testing results will not always be shared in a responsible way!

I also liked the chapter where Clancy showed images of pregnancy materials at 5, 6 and 7 weeks for pregnancies that have ended. The ruler at the bottom of the image are very helpful to give context to the size of the fetus.

I did bawl like a baby probably about 10x while reading this book, so definitely take care if you are someone who has experienced pregnancy loss or have experienced "Obstetric Violence" which is defined in the book as the "mistreatment, disrespect, abuse, and neglect of pregnant people, especially during labor and delivery." I didn't know there was a word for what I experienced with the birth of my second child, but I am glad to have it. Clancy talks about how this violence is often justified by healthcare providers to deliver a healthy baby at any cost.

Highly recommend.

Thank you to Princeton University books for providing me with a physical copy of this book.

I absolutely loved this book. It fills such an important gap in the literature around conception and early pregnancy; particularly that strange, uncertain period when you may be pregnant, but don’t know yet, and how little we actually talk about or understand that experience.

I was fascinated by the evolving science around conception, implantation, and early pregnancy, and genuinely could not believe how much of what we think of as settled knowledge is still changing. The discussion of emerging evidence around just how variable the timing of implantation may be absolutely blew my mind.

But what I appreciated most was how much bigger this book is than the biology. It examines the way women’s bodies are monitored, judged, and policed during pregnancy, often beginning before a pregnancy is even confirmed, and asks really thoughtful questions about what we expect women to do with uncertainty and risk.

I also loved that it doesn’t treat pregnancy as one universal experience. It considers race, class, incarceration, access to healthcare, and the experiences of women who are so often left out of mainstream conversations about pregnancy and reproductive health.

Such a fascinating mix of science, history, medicine, policy, and lived experience. A must-read for anyone who has had a baby, is trying to have one, wants kids someday, or honestly just wants to understand how much we still don’t know about the very beginning of human life.

It seems morbid that I am interested in books about death and loss, but I am very interested in medical stories and the science of how our bodies work. This book may be emotionally difficult for people who have lost a pregnancy to read. I am able to take an objective perspective because I have not experienced that trauma, and I recognize that privilege. Clancy explains the different reasons why pregnancies do not make it to term and explores the science of how they happen in the first place. She examines the reasons why maternal health is not prioritized and the societal factors that influence pregnancy losses. I was fascinated, and I'm currently reading her previously published book on menstruation.

Read for work, some interesting tidbits for sure but also probably five years too early for me to be reading this

Super informative and interesting. Definitely focused on pregnancy loss, so take care if the topic is triggering. Having lost a pregnancy more than 15 years ago, I found it a bit cathartic.
