Hey ladies. I don't post on here often. I was diagnosed with PCOS July 2016 and that time my period was very irregular. I was put in Provera to start it and Metformin 500mg 3x a day. I had an ultrasound and everything looked good. My Gyn said were clear to start TTC. I'm currently on CD18 and I believe my opk is finally positive. ?? We BD 2x yesterday and 2 nights ago. We also used Preseed last night too. Should we BD again tonight just to be safe? TIA.
