I had oral sex and I know it's very unlikely to become pregnant, but my boyfriend and I tried anal sex but we didn't actually do it he just touched it and before this he washed his penis before "attempting anal" which we didn't what are the chances if pregnancy if there was any pre cum? Should I consider taking plan b or should I be fine? I just ended my period on Monday. I'm an irregular period as well. I'm a 34/36 day cycle. There was no penetration involved. Thank you!
