Infertility/Fertility/Crinone during pregnancy


I'm from the U.S. After a long struggle with secondary infertility and 2 miscarriages, I am pregnant again, 9 weeks along. I'm on supplemental progesterone, Crinone 8% once a day. When can I feel okay about stopping the Crinone? I was supposed to see my doctor in 2 days, but he experienced a family tragedy, and I'm not sure when he'll be back. I think he had talked about stopping the Crinone at 9 or 10 weeks, but I was going to confirm that with him at my appointment, and I have no way of asking now. Thank you for your time.

Hello Maria from the U.S.,

With your history of 2 miscarriages, I will usually be very conservative and continue the progesterone until 12 weeks gestational age.  However, medically, it would be okay to stop at 10 weeks.  By then, the placental should be fully functional and providing all the hormone necessary to maintain the pregnancy.

Good Luck,

Good Luck,
