Pregnancy My Pregnant Life When should I tell my boss that I'm pregnant? By Parents Editors Published on July 2, 2015 Share Tweet Pin Email Q: When do expectant mothers usually tell their employers about the pregnancy? A: Medically speaking, I warn all of my patients against telling anyone they are pregnant until after 12 completed weeks, as the highest risk for miscarriage is the first 12 weeks of pregnancy. However, I do not have any first-hand knowledge as to when women generally tell their employers about a pregnancy. Answered by Dr. Marra Francis Was this page helpful? Thanks for your feedback!
