Extreme mood swings

So I have been pregnant for 10 weeks now and I cannot control my emotions, I get so angry and I really can't control it but my partner is saying I can somewhat control it, no matter how much I tell him I can't. He doesn't understand and we have been having fights on how he feels unloved when I have my mood swings and I do end up apologizing to him but as I said they are extreme. Sometimes I wish I wasn't pregnant so I wouldn't hurt him and so it wouldn't be my fault for all of our fights and when I'm too tired to do anything. I just need some advice to where I can control my emotions and maybe this wouldn't be my fault anymore.
