Had sex on period and he cum inside me. Help

Hey so my boyfriend and I had a bit to drink together and well one thing lead to another, sex on period and he cum inside me, which I didn’t know about till afterwards. Didn’t phase me at the time

But just thinking, I know there’s a tiny chance u can get pregnant but is there really, anything I should be concerned about. Like we have unprotected sex now and then, but it’s cause we are to in love and love the feeling, always finish the sex with a condom on though.

So just needing a little girls advice, help, suggestions on this kinda thing. 😀 thanks girlies
