Annoyed Bipolar Pregnant 😩

I am just over six weeks and I have had such a short fuse everything is setting me off. I usually am pretty passive but I can't even stand my husband breathing the wrong way. I know I have to be withdrawing (heavy coffee drinker and smoker) but does this go away or get better down the road I really don't want to get a divorce because I am a wicked witch when I am pregnant. (I'm not exaggerating I literally am making myself mad)
