Got engaged over the weekend. No condom, so we did anal...very stupid, I know. However, he came right outside the anus. I immediately jumped in the shower to rinse off everything, because I did not want any sperm contacting my vagina. I'm still paranoid that something did contact my vsgina, because i was possibly on one of my last ovulation days. Less than 48 hours later, I took the Plan B pill. Is there a high risk of pregnancy still? Will the pill still be effective, even if i took it after ovulation already occurred? Help!!
