I never had a period in MS/HS until I went to the doctor and they put me on birth control when I was 16-17 and I was on it for about a year and then I quit. I got back on it when I was 19, I was on birth control from 2008-April 2015. My period is so irregular that I have no idea how to tell when I'm ovulating. Where do I start to try and figure my system out? I just turned 27 and my husband and I are coming up on our 2nd wedding anniversary. I have been trying to accept the fact that it will happen when it is supposed to, but that isn't working very well when everyone I know is getting pregnant whether it was planned or not and I am trying and can't.
