He came inside 😬

Hi friends 😇 so since my 2 year relationship ended in November recently I’ve been having a bit of fun with a couple guys, especially this one, John 😍 we hook up like once a week and last Sunday I let him cum inside me. I’ve only let a guy do that once before. That day was the final day of my period and I’m also on the pill. I’m a little scared i could be pregnant but probably not?😬😂 also, five days after the sex I think I still found some semen in my vagina?? How long can semen stay up there for?!? Thanks girls 🥰😘
