So my AF start day is tomorrow, February second. Normally I have cramps and get really pissy two days before but so far nothing. My breasts have been hurting really bad, my sex drive us insane, and 3 days after my peak ovulation day I had a tiny bit of spotting but no cramps. Then it was gone before the day was over. I took a test two days ago (12 days po) and got a bfn. So why should I do?
