Awkward sex and pregnancy question😭

Hey guys I feel embarrassed talking about this but my husband and I have an issue. We both were trying for a baby and now that I'm pregnant (not even ten weeks yet) I'm scared to have sex because of my previous misscariage and Because of extreme nausea I am hating sex Soo much. My hubby has been extremely nice about it but because we were making out Soo much while we were trying he kinda feels like I have changed, he is nice about it but he seems sad. We have had sex once this week but I have hard time kissing Hime due to nausea and for some reason his breath make me wanna puke, like I'm gagging typing this. Not because he has bad smell but because I'm being a super smeller and hating everything..I had no idea my early pregnancy will be this horrible but I feel like I am making him all weird because he went to sleep mad at me because I couldn't kiss him, I give very quick ones but he knows what's up. I asked him and he was like I'm not mad you but I feel sad that I am causing nausea for you. 😓 Please tell me what to do, or how do I stop being like this when near him.
