Hi Don,

First of all, I am so very sorry for your losses, big Don't worry about going on about yourself, that is what we are here for!

I have been taking progesterone pessaries as part of my fertility treatment not for miscarriage (even though I have had 2, maybe 3 ) but I would imagine that things are the same regardless of why you are taking it. My clinic start me on it 1 day post ovulation, they said that if you start it before O that it can make the endometrial lining less receptive to an embryo if there is one. So yes you are right. I have cycle tracking (bloods and ultrasound) to monitor when O occurs so I know when to start the prog. I don't really know what I would do in your situation, maybe BBT so you know when O has occurred and start them once you see a temp rise? Or test with OPKs and start the prog a couple of days after you see a pos?? Sorry I can't really be much more helpful that that, but I hope some of this helps you. Can you at least talk to your ob on the phone about it all? My FS is available by phone whenever I need him.

All the very best xx
