I'm on provera to induce af because I've always had irregular cycles. Thing is...ever since I've been on my medication my cycle has been good for almost 2 years now. After my last provera pill it usually only takes 2 or 3 days for af to start and so far nothing yet. I'm confused? Last Friday..the day before I expected af I had unusual cramping sort of similar to af cramps but not really. I just thought here come the witch...but nothing yet. I haven't tested today, yesterday was negative. I'm supposed to see my dr on cycle day 1 to start my first round of clomid but af hasn't shown and I'm getting a little concerned.
