sex help

Ok so back story I am married with a 10 month old and I am 21 weeks pregnant. Ok so I have no sex drive I want to please my man but he says he does not feel the love when I give him a blow job or a hand job. I don't know what to do now I don't want to do anything. Any ideas and how to make him happy no matter how much I try to like it I can't even fake it. I feel like I am failing him. He is a very sexual person but this pregnancy has taken my very high sex drive. Advice please!!!
