"From New York Times bestselling author of Expecting Better, a guide to navigating a second pregnancy when the first did not go as planned-with Dr. Nathan Fox, Maternal Fetal Medicine specialist. In Expecting Better, Emily Oster revolutionized the pregnancy landscape with her data-driven approach. In the years since, she kept hearing questions from readers on how to approach a second pregnancy when the first has not gone as planned. The Unexpected is a book that Oster hopes no one needs-but in reality, 50percent of pregnancies include complications, and we don't talk about it. Preeclampsia, miscarriage, hyperemesis gravidarum, preterm birth, postpartum depression: these are lonely experiences, and that isolation makes treatment harder to access-and crucial research and policy change less likely to happen. The Unexpected lays out the data on recurrence and treatments shown to lower or mitigate risk for these conditions in subsequent pregnancies. It also provides readers roadmaps to facilitate productive conversations with their providers, with insights from lauded maternal fetal medicine specialist Dr. Nathan Fox. By bridging the knowledge gap and making space for difficult conversations, The Unexpected promises to make the hardest parts of pregnancy a little bit less so"--
