Today I had sex and we did anal 1st and that was without a condom and when he came he came in my 🍑. He pulled out after that and some cum came with it and it got on the outer side of my vagina but pretty close to the hole. Then I went to the bathroom after we finished anal, then we had vaginal sex with a condom and that was it. I'm not on the pill and my next period is supposed to be in 10 days. Should I get plan b just to be sure? Or should I be okay??
