So Its my first round of clomid this month. I am on cd 12 and I took the pills cd 3 thru 7. For unexplained infertility. For 3 days I've been getting close to positive opks but never quite the surge. Am and pm testing. Now today I started cramping really bad so I was almost positive I'd get a positive opk. But nope. Can anyone on here tell me their clomid stories? Is it normal to cramp like af cramps???
