So according to Glow. I had sex exactly on my ovulation day. He did not pull out and I don't use birth control. Is there a high chance of pregnancy? Currently on another app I use regularly it says I am 2 days late but Glow says my period will start in 2 days. My nipples have been sensitive to the touch for 2 days. I can't even rub a towel on them without hurting. Other than that I don't have any pregnancy symptoms. Should I wait to take a test? Or should I go ahead and take one?
