Sex..Sounds good but no energy

I've been with my husband 6yrs , and we've never had a problem with sex, or us wanting to have sex, now that I'm pregnant I can't remember the last time we did. I'm going to be 3months tmrw and I think we had sex about a month ago? 😕. We are really affectionate and always hugging or kissing we just don't have sex. The thought of sex sounds nice but having the energy do actually go through with it is a different story..I would really like to feel that connection again but not sure how the start 😕😟 any one else in the same boat?
