So a couple days ago I made a bad decision to have unprotected sex, and my boyfriend never finished. But we were both worried about pre cum. He told me he doesn’t think he had pre cum cause I had finished him earlier. Anyway, I went and got plan b about 12 hours later. I was told it’s a slim chance of getting pregnant off pre cum. I have a very irregular period so I wouldn’t be able to really have any signs of pregnancy. Do you think I will most likely be pregnant?
