Angry that I might be pregnant

I told my husband I might be pregnant and he’s super angry now. I had a chemical around Easter and we were both crushed and agreed we’d try for a baby at the beginning of 2020. Well, there’s a pretty good chance I’m pregnant now, unplanned. And he’s not happy. I don’t know what to do. I want to enjoy my pregnancy with our last baby but he’s ruining it. This will be our 3 and he hasn’t been happy about any of them but this time is the worst.
