We were having sex and I was on top of him, sitting with my back turned to him. And after all that, when I got up, he noticed that the condom got stretched out a little. It didn't tear, it just slipped out a little when I got up. He hadn't came. And I was on my second last day of periods. Do I have to scared of being pregnant? Just I have tender breasts and slight cramping but nothing else at all. Cause when I researched, they say that ovulation can occur during your periods also and also my period cycle has been really irregular this year. Got it in Jan, twice in march, skipped in April and feb and 2 weeks late in may (after intense cramping)
