I'm really frustrated. I'm in our first cycle of TTC..my cycles are usually 34 days long with the odd longer cycle about every 6 months or so...now cycle day 35, BFN yesterday and the day before. I have had terrible cramps on and off for a week, they got worse yesterday night and I had to take a painkiller, and I was certain period is going to come, but nothing. Why would I be cramping if I'm not pregnant and why is my period not coming? I usually ovulate around CD 20 but we only managed to DTD CD 10, 11, 12, 16 and 24 this cycle and I had awful cramps CD 22 where I couldn't move, I think it could have been an ovarian cyst or something as I've had corpus luteum cysts before. Should I just wait for my period to come?
