So I had sex a weekend before I was ovulating unprotected and then the day of my ovulation day the most fertile day unprotected and also a few nights ago unprotected some ppl are saying no I can get pregnant some are saying it’s possible including my friends but according to this app on my ovu day I was most fertile so I’m just wondering if anyone had luck following this app or if I should be looking soon for that little plus sign I know I should take one any way just bec of all the times I’ve had unprotected sex but about a week ago I did have very light spotting it stopped and then a few days ago I had a little blood when I used the bathroom a few times idk if that could be a sign of implementation-bleeding or spotting b4 my period I’ve never been pregnant so jw what to be on the look out for
