Slip up?

So my boyfriend and I were having sex and he finished. We then decided to mix it up a bit and try it in the other hole. We put a fresh condom on for lubrication ( didn't have lube ) and it didn't exactly work that way so we decided to try it without the condom and let's just say he slipped back into my 🙀 . Should I be worried? Condoms are the only sort of birth control we use 🤕
