Need some advice please . !!

Hadeel • Baby #1 due aug 20th! :)))
I am 9 wks Prego and I have symptoms were I don't want to have sex .. Always nauseous and tired! My husband thinks I'm cheating on him bc I won't sleep with him. We got in a argument bc he saying I am acting too guilty bc I was yelling (hormamonal). I was explaining to him that's how I feel during the 1st trimester but he just didn't want to believe that. Now we're not speaking and he is making me feel like it's my fault Like I actually did something ! Any one else go through something like this?! Any advice
