4months pregnant and sex hurt

Usually it’s good

He rubbed my clit until I came and then he put it in and it hurt, like burned... the sex was kind of uncomfortable I was going to tell him to stop but I could tell he was coming and then I got turned on.. so he came and stood in me and I had to tell him if he was done to pull it out . It felt really tight too and dry but I know I wasn’t dry cuz I was really wet.. I cleaned my self up there was no blood and even went to go pee and everything was ok no pain no bleeding... what could of happened ??
