Whirlwind of events

I had sex earlier today. Not my first time but I’m still pretty new at it. Okay cool. But today a whirlwind of events happened. The condom fell off. IN ME. Didn’t know until we both finished. Had to fish it out. For me to find out I was also bleeding. Not sure what caused the bleeding. But it was there. I think he came in the condom, but we honestly don’t know. 😬 I have a nexplanon so I’m no AS worries but I do still worry of course. But I’m also a month and a half out from gastric bypass so I’m seen as highly fertile. Which is why we also used the protection too. Any thoughts?
