So confused ladies!

Cheyenne

So OPK was at a peak 1/18, estimated ovulation was 1/19. BF and I had sex 16,18,19,20 mutiple times a day. Expected AF was 2/2. 2/3 i had very faint spotting, now 2/4 and still no AF. Took preg test 2/2 BFN...is it possible I need to wait longer and test again??

Ive had a few weird things like super gassy, constipated, not feeling well, tired, but no sore breasts...I'm so confused???
