Ok who’s right?!

So tonight at 9:00 my husbands friend decided to knock on the door and bring another friend whom I have never seen before over , completely unannounced. My husband let them in and I fled to the bedroom because I’m without a bra just after a shower and getting our 2 year old down. I was furious they didn’t give a heads up but my husband is saying I’m overreacting and that that’s what friends do is swing by when they’re in the neighborhood . I said your friend is a grown man who knows we have a small child he needs to ask if it’s ok first but my husband is so mad that I’m not ok with this because I’m “uptight” and “mad about everything because I’m pregnant.” What would your reaction be? Am I being too dramatic?
