Yesterday me and my boyfriend got in the shower together, he released his sperm on my face, while I was kneeled down on the shower floor. I made sure to keep my legs closed tight together but I'm worried as to if some of his sperm or pre-ejaculation got into my vagina. Could I be pregnant? I should get my period on the 13th of this month, so I only have 11 more days to wait until my period comes. I'm just worried and I tend to over-analyze everything. Please, help? Should I just wait and see if my period comes?
