So my husband and I are ttc. Only one month so far so not expecting anything anytime soon. Anyway we had sex January 24th my fertile time. My AF was supposed to come on the 5th of February and didn't show. It's never late. Maybe a day or two early but never late. I was experiencing symptoms that I never had and my body felt off. All test said negative. Anyway finally AF showed up 8 days late on the 13th. Now it's 15th and she is now gone my pad is clean as if unused and when I wipe nothing. What could this be? I had dr appointment today but cancelled since AF came they told me to go tomorrow morning just to check.
