I haven't had a period since I started the depo shot 7+ years ago. I got my last shot Sept 30, 2017 and still have not gotten a period. My husband and I are TTC. I was diagnosed with PCOS in April and put on metformin, and was told to start prenatal. I finished 1 round of provera last week, and still haven't had a period, my OB said if I didnt get a period by the 21st, I was either pregnant or it just didnt work and then we would try clomid if it didnt work. the last couple days, I have felt some cramps, similar to period cramps. but no spotting or blood. I'm not sure if I should just wait til the 21st or take a test now. anyone else have similar issues/problems? advice?
