Sex guilt?

Anyone else feel guilty for not having sex with your husband/SO much anymore? I’m 30 weeks and we haven’t had sex in a couple weeks and I just don’t feel up for it at all... he is such a good sport about it and doesn’t complain at all and totally understands, but I can’t help but feel bad! I just don’t feel up for anything sexual... like I don’t have a horny bone in my body right now lol
