So I had sex a week ago with a condom but before we put it on we were grinding on each other with my panties still on for a very little time like 2 minutes. (Could it be possible to get pregnant if he had a little pre cum ? )Before that day I was already 3 days late on my period and now today I’m 8 days late. Yesterday my nipples started to feel sore doesn’t usually feel like that before my period since i was younger. (What could that mean?) I know stress could cause late period I just started a new job lol could be that but I’m not super stressed about it. ( what are other reasons why a period is late?)
