Me and my boyfriend had sex on my fertile window that was Nov. 18. We used condom and even changed three time. Just lately I learned that one condom ripped and the other one slipped halfway his penis. I didnt knew that the time we were having sex.Altho he did not came inside me.My period got delayed for 3 days but it came. Tho it was not heavy as my usual period. Now Im dizzy and my breasts are tender for almost a week now. Should I be worried that Im pregnant tho I got my period? Thanks xx
