No sex since June

Since I found out I was pregnant in February (I'm due in 28 days!), my husband does not want to have sex with me. I literally can count one one hand how many times we've had sex during this pregnancy. I've talked to him about it, and he says it's gross to him, not that I'm gross, just having sex while I have a baby growing in me is gross. He's been very stressed with work and financially we are struggling. Anyone have suggestions? I mean, there isn't much to do now since I'm basically ready to pop. But anyone else go thru this?
