I'm just wondering if anyone has had period like cramping during ovulation? I believe I'm about to ovulate, and I'm having an achy cramp, not quite as bad as period cramps but enough to notice they're there. I'm just starting to get a change in CM, and I have not gotten a positive OPK yet, but I'm sure I'm going to be ovulating within the next few days, any input?? Thanks in advance!
