Big darlin. I concieved this pg on clomid too, it took me 3 rounds but i got there. I had progesterone monitoring 1 cycle before i started and then every cycle i was on clomid. BUT i had progesterone pessaries to support/ lengthen my luteal phase and maintain the pg. And i think it's working, i haven't had an alive baby at 10w since my son.
I hope you can find a good FS, that will support you through this horrible journey. My OB gives me weekly u/s per my request, and emergency appointments if im cramping (i have a serious bladder infection it turns out) I think it's so important for your peace of mind, your already going to be terrified enough next time IYKWIM?
If you need anything feel free to PM me, do you know what tests they have done?
GL sweetheart, keep us updated and i'm thinking of you xoxox
