Help I don't know what to do!!

I'm 12w1d today and all me and my boyfriend do is argue before in our relationship I wasn't so faithful but I have changed tremendously but all he ever does is bring it back up. I cry at the drop of a hat and it stresses me so much , arguing with him on top of a full college course load!! I always tell him stop picking arguments with me because its not good for the baby at all , but its like he doesnt listen to that he always says im blaming stuff on my hormones , I just feel soo miserable and not even baby happy anymore I don't know what to do 😞😞😞😞
