stselling 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.

While The Unexpected is a book that Oster hopes no one needs, the reality is that 50 percent of pregnancies include complications, a fact we don't talk about. 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.

A reassuring window into what can feel like weighted unknowns, The Unexpected lays out the data on recurrence and treatments shown to lower or mitigate risk for thirteen different conditions and challenges that may impact subsequent pregnancies. It also provides readers road maps to facilitate productive conversations with their providers and make diagnosis and treatment more efficient, 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.
