pain during sex. 3rd trimester

Emily
Im 30 weeks today, and for the last few months it's been really uncomfortable/painful to have sex. My husband is really great about it, and doesn't push me. However I feel bad not being able to have sex with him. I used to have the higher sex drive out of the two of us. So this is super weird, that I have little to no interest. So my question is; is it normal for it to be painful during later pregnancy? If so when will it go away? 😩
