Lack of sex

My husband and I had sex once last month. We had a couple stressful things happen and I know that was part of it, but I still feel terrible about it. We are 8 months pregnant and it’s making me feel like he’s just not attracted to me. Yes I know that this is most likely the emotional hormones, but it’s hard when we go at least 2-3 weeks with anything. I’m starting to loose my mind! Any tips/tricks or any one else in the same boat?
