Hi About 3 weeks ago I had oral sex and when he ejaculated some got onto my fingers but not a lot  I immediately went to wash it off in the sink with hot water and soap. I had clothes on the entire time I didn't touch near my vagina or anything before or after. Now my period is back but it's lighter I was told it's because of stress but I'm not sure is it possible that I could be pregnant?
no oral sex won't lead to pregnancy....it's only semen going inside vagina thru intercourse...travelling thru uterus til tubes to fertilise eggs...don't worry..
