I think I saw in an earlier post that you have had normal cycles for the past year. I just recently started having "normal" cycles so long as I was actually ovulating from getting a trigger. My cycle got messed up last month and my follies werent big enough for a trigger so my dr said wait for a new cycle to start and we would try again. It normally takes me forever and a day to start a cycle if I don't trigger so I took it upon myself to take Provera to force AF...usually I start 1 to 2 days after the last pill but it's been quite longer than that and I am getting very sore and uncomfortable. And the pain is just lingering and constant.
I haven't had any spotting etc, just the cramping and really sore bbs. Not sure if this helps in your case, but hopefully it shed some light.
