Help me. First time mom

Is it normal to be having uterus pains off and on for hours after having sex.? Like it feels like contractions but not getting worst or lightening up. And my uterus is at a constant pain too. It hurts to walk, lay, sit, and even when trying to get comfy. I didn’t have an orgasm but he did cum inside of me. Then I had this come out of me during sex, it’s like jelly and has a yellowish tint to it. No smell and I’ve never had it before. I’m 33 weeks pregnant.
