Nausea during sex

I am 13 weeks and 1 day 💖 a little before I found out I was pregnant (10 weeks) I wasn’t in the mood at all to have sex with my so. Like at all, idk I just wasn’t getting turnt on what so ever. Now, it’s like that feeling has gone away just a little bit but now when we start I get very nauseous and feel terrible! Is this normal?? It’s like almost everything I do gets me nauseous but sex?? He was bummed out that I said I wanted to stop lol but i COULDNT helped it’, I got dizzy and felt like I was going to throw up on him.
