overly stressed out help!

Katie • ♥️🌈💍
So I'm 8 weeks pregnant and all of a sudden my husband has no temper has been lashing out very high strung and it's stressing me the F out!!!!! 
Like to the point he is yelling at me for no reason..
So I've noticed when this happens I get cramps
And I'm wondering if this is normal?
I'm just so nervous I'm going to have another MC from him stressing me out
😕
