Hello Doctor, I m really scared and please need your help. I m 31 years old and my periods are very regular, I almost get them 4-5 days prior to my previous start date. My last period ended on the 4th of April and on the 8th day of my period, that is on the 5th of April, me and my BF made love but he did not penetrate. He had precum on his penis and wiped it with a cloth. Accidently I ended up using the same cloth to wipe my vagina a few seconds later. I m really scared now, could I be pregnant? Is it possible that sperm, in case it was there in the precum, could swim in? Please help.
