Sex during pregnancy....

So throughout this whole pregnancy (I'm currently 31 weeks + 5 days) me and my SO have not continued with our sex life. We haven't had sex in probably 4 months, he doesn't want anything to happen to the baby and in just so sore and tired! It may sound silly but has anyone ever gone this long without sex while pregnant and then started having it again? I just want to know if anyone experienced bleeding or other things during this time. 👶🏼
