Disappointing

Had my period March 1-6th. Then again March 25-30th. Started ovulation testing. They said I had high fertility April 3-10th and peak was the 11th. We didn't BD the day of peak but we did the next morning. Obviously that wasn't good enough. Started my period this morning. I never know when my period will happen anymore, ever since I had my first baby it's been irregular. This sucks. I was really hoping we were pregnant. Ugh.
