Am I overreacting

I am six weeks pregnant and my emotions have already been running wild. Me and my boyfriend got in a huge argument last night, then a small one this morning. He took it upon himself to message his mother and sister and told them he doesn’t know if he can do it anymore and wants them to “fix my hormones”. So I get a text from his sitter saying “call my momma” and didn’t even know all those details until I texted him to ask wtf was going on, it was like a set up. Is it just my hormones making me over react? I’m not close to her by any means and I don’t understand why he needed to bring them into our relationship issues?
