Sex hurts!

Keek

So I'm 32 weeks tomorrow. Just had sex with my husband and it was painful. So painful I started to cry. I was just trying to get through it so that he could finish. I dont know for sure, but I dont think sex is supposed to hurt ever. Maybe be uncomfortable, but this was painful. Felt like he was hitting something that he shouldn't of been. My cervix maybe. Should I bring this up to my doctor tomorrow or just not have sex again for awhile?
