I don't know what to do

My husband and I agreed to tell everyone about Our baby after our first appointment (April 10th). A friend/coworker figured out I was pregnant. She said she could "just tell", so she knew found out a couple days ago. Anyways, my husband found out tonight that she knows and he's extremely mad at me and says I took all the excitement out of telling people for him. I don't know what to do. I didn't mean for her to find out and I didn't plan on telling her. I wanted to wait and tell everyone with him too. I obviously don't want him to feel the way he does, but nothing I say helps.
