Thank you, thank you, thank you for your reply. I have actually miscarried again since I posted (was pregnant then and didn't know), so my husband and I will be visiting a high-risk OB that I know and adore and will have some extensive testing done. Pretty scary, but hopefully we'll get some answers. With luck, we'll have a baby during my 4th year and I'll take at least 9 weeks off. Congratulations to you and your new baby! How did your med school react to your pregnancy and need for maternity leave?
