Help!

So I’m 34 weeks pregnant and i haven’t been able to have sex at all. I just feel gross, unattractive, fat, I’ve just had very low self esteem lately and can’t bring myself to want to have sex. I have no sex drive at all. My husband really does try, I just can’t stop myself from comparing myself to everyone else. I feel awful about myself. I keep having sex dreams, and I’ll wake up and be in the mood, but it quickly goes away. But in my dreams, I’m not pregnant 🙄. I know it’s almost over, but is there anything I can do, or take that’s safe during pregnancy that will make me horny? Probably a stupid question, but I would my husband to get some before I absolutely can’t for at least 6 weeks.
