Spicing up things in the bedroom

Currently 15 weeks pregnant and my sex drive is still very much here. I just feel like I’m so tired by the time my SO gets off work and decompresses and wants to have sex 😂 It’s to the point where it’s almost like a chore instead of intimate but it’s not like he forces me or begs. We both want it I’m just tired these days and I’m not sure how to make it more enjoyable. Maybe 1 day out out of the week I’ll be super ready but the other days I’m just like bleh.
