My husband is acting resentful

I'm 8 weeks pregnant and feeling like absolute garbage. I feel like I can barely function, but I have a 2 year old that I'm trying my best to take care of as normal. He takes any energy I have. I had 2 losses before this, the first one I had severe nausea for about 12 weeks and when I lost that baby I had a really hard time coping. My husband was very supportive because he knew I was struggling.

This time around the nausea is just as bad. He continues to want sex, of all kinds, but I just can't bring myself to do it. On top of feeling sick 24/7 I'm just not in the mood. I told him it's not going to be like this forever but I can tell he's getting annoyed and starting to resent me. Doesn't really seem fair to me as I'm the one suffering. The only suffering he has to deal with is not getting sex for a few weeks. Should I suck it up or should he?
