No sex for me

I’m posting this anonymously because I’m so embarrassed. I’m almost 17 weeks pregnant & my son is so low that I literally can’t have sex. He can barely get in before I’m crying in pain. It’s like he’s hitting something that’s super sore & I can’t take it. We haven’t had sex in like 2 months. He’s so sweet about it but I feel horrible. Any advice or tips?
