Femara ladies plz help

Hi ladies. I took femara cd2-6 ths mnth for the first time ever. I’m on cd13 now if a normal 26/27 day cycle and I dnt feel any ovulation signs at all. I have watery cm since last week bt nothing else. Before I wld feel pelvic pains and sore nipples at cd11/12 of every mnth when ovulating. Does femara change all that?? Help it’s my fertile week bt feel like femara has messed with me n I dnt know when I’m ovulating. opk’s r randomly light n almost as dark as control line each day (test twice a day) I hvnt seen a line darker yet
