Arguing while pregnant

FTM here. I swear I probably overreact over everything I do. I’m constantly googling everything I did that I think may have harmed my babies (yes I’m having twins). So my husband and I just had a little argument. I raised my voice but didn’t yell. I could feel myself getting mad. Now I’m worried that I’m causing harm to my babies. I’m 31 weeks. We have small arguments every other day over stupid things. Nothing big but like I said I could feel myself getting mad this time but not stressing over it.
