Advice needed please!!!

I’ve been with my husband for 7 years married for 6 years. We tried 5+ years to have a baby. Well I’m july 2018 we got pregnant and now I’m due April 23rd. Which we are excited about. But our sex life is lacking a lot. 😭 we’ve maybe had sex 5 times since I’ve been pregnant. I just don’t have a sex drive at all maybe 1% of one. I feel fat and ugly. I would “spice things up” but I honestly don’t know how. I’m really not into lingerie because of being self conscious. I don’t roleplay as I obviously don’t know how either. 🙄😳 even fore play i feel I’m not good at head so I don’t do it. He doesn’t do it either so I feel why do it to him if I don’t get it back. Even when I’ve tried I don’t get anything in return (which I don’t expect at all but the thought of it would be nice ya know?!!). We’re into toys, anal and stuff but it feels so limited on what we can do to “spice it up”. Does anyone have any advice or helpful tips. I know I don’t give a lot of what we can do but anything will help!!!
