Hi Sir/mam, I Usually Have A 28 Days Period Cycles.

Hi sir/mam,

I usually have a 28 days period cycles. It's been 27 days today. Last week wen I was in my fertile period, I had intercourse with my husband. We used protective measure. But unfortunately after intercourse his condom was stuck inside my vagina and his semen was in condom. I m scared that I would get pregnant. Is it possible of me getting pregnant? I washed my vagina immediately after intercourse. Is there any possibility of getting pregnant if any one or two drops of semen went inside my vagina unknowingly
