Hi Numa,

I am on Progesterone Pesseries and have been since my ET. I am 11 weeks pg today and my doctor has advised me after my ultrasound last Tuesday to start to halve my presseries and then halve them again next week and finally stop them on the 12 week mark. I wouldn't just stop them I would check with your Fertility specialist to make sure everything is OK with baby.
Good luck, I can't wait to stop my pesseries.
