Help!!!

Okay so I just hooked up with this guy. I had the skyla IUD inserted about a month ago. Anyways, I didn’t see him put on a condom or take it off (I know I wasn’t being smart) and I can’t tell if there’s cum in me or if its just from me. But the shady part about it is that he sent me a Snapchat of a condom after I left and said “I almost laid on it lmao”. I think he might’ve just sent that to make me think he used one 🧐🧐 my question is, should I take a morning after pill? I still have the IUD but I am just paranoid and something doesn’t feel right.
