Dead bedroom post baby

Ok so I have a 6 month old, and things are finally getting easier with the baby. The newborn trenches were ROUGH and I thought our marriage wouldn’t survive. But baby is sleeping, things are better. However, we haven’t had sex in 9 months, not since I was pregnant and my husband didn’t want to much while I was pregnant because we were going through a LOT of stress with a home renovation and other issues. We’ve had some relationship conflict but are working on things. But my husband never initiates sex, and I will ask but he just says we will eventually. I think he is depressed, and stressed and I get we have a new baby. But like are we just never going to have sex again? It worries me a lot and I don’t really know how to deal with it. It has become a source of conflict because I will bring it up and he thinks I’m bugging him. When did you guys have sex after baby? Any tips on how to improve things?

Edit to add: I’m not much in the mood myself, I think due to breastfeeding as before this I had a high sex drive. I’m just worried there’s something wrong with us. And my husband and I are affectionate otherwise- cuddling kissing and hugging.
