This pregnancy is making me so irritable

I get annoyed and frustrated with the tiniest things and my fuse is so short. I’m never ever like this. I have the most amount of patience out of everyone and am generally very calm and laid back and rarely argue with anyone. I hate this and hope it goes away. I was never like this with my other pregnancies and my husband doesn’t know how to help, it’s like he’s walking on eggshells and I’m only 7 weeks. How in the hell are we going to survive the rest of this pregnancy omg
