We've been TTC for around 5 months. I got off BC in November, and I believe I had a chemical pregnancy that month. December was a normal period for me (29 day cycle, 4/5 of actual period). January it was only 26 days, 2 days of bleeding. February was a 25 day cycle but more like 4 days of bleeding. and now March was 26 days again but 2 days of bleeding. As far as the 2 days, it's not light the first day and a half, it's normal flow (sorry tmi for all of this). I chart and use OPK so as far as those two things, I'm ovulating on the 17th day- which is normal for me in a regular cycle. I've never had this before even off birth control. It's making me thick that I'm not building up enough uterine lining for a pregnancy.. any ideas??
