So confused

I’m 7 weeks and since the week I ovulated I’ve been so irrationally irritated by my boyfriend. So much to the point I’m questioning the relationship and not sure what I actually feel anymore. Our sex life is nonexistent anymore. I know he’s worried and not happy with the changes. I don’t know if it’s hormones or if the honeymoon stage is over, we’re only together a year. Or if I’m just apprehensive and putting my guard up, my last relationship (of 8yrs) ended after we had our son! What’s going on with me 😩😩 any advice would be great. The pregnancy has me feeling miserable.
