I am on Femera, my doctor pinpointed my ovulation around the 29th of November (which I thought I cramped the 28th of November, the Tuesday before I had what I thought was the fertile mucus. I haven't used the kits, I figured I was too late when I thought of buying one. Last night I have again what seemed to be Fertile mucus, and I had cramped most of yesterday. Not sure if I ovulated yesterday or last week. Anyone else have this happen to them??
