Am I good?

Hayley

So I got my Mirena put in just over a month ago. I’ve had my period for 11 days today but had sex with my boyfriend tonight and he came in me. Will I be good? It’s the first time he’s cum in me so I’m pretty worried. He’s also told me that not being very fertile runs in both his mom and dads sides of his family.. idk am I

just paranoid?!
