Soooo I’m not on birth control, I’m in my mid 30s and had been on it since I was 19. I got off of it last January for health reasons. I have been dating my boyfriend for a while and we’ve just always used the pull out method. I know that’s not the greatest, which is fine cause if we’re pregnant then we’re happy, just not actively trying if that makes sense. Anyway... was tracking my period and ovulation, had sex when I was NOT ovulating, according to the app and now I’m 8 days late on my period. I am extremely regular when speaking about my period. I took at test at 5 days late and got a negative result. Any ideas?
