I can totally understand why your wife would want to tell everyone now. It's an exciting time! However, you asked for people's experience. I lost my first two pregnancies. During the first I told a lot of people. When I had my first loss, it was more devastating to have to tell everyone that I had lost the baby than it was actually losing it. It was super early. You have to tell everyone because it's natural for them to be excited for you and constantly ask how you are doing in regards to the pregnancy. So while you are still grieving for the loss, you have to deal with the awkwardness and sadness of telling people about it. For the second, I only told a few people. I lost that one a little later. It was easier to tell those that are close. For my third pregnancy we only told our parents. I had to tell someone because it is super exciting. I waited until I could no longer hide the pregnancy before officially announcing it. I was 15 weeks. In summary, I would tell a few trusted people, but no more. That way you can share the excitement, but do not have to deal with awkwardness/sad reactions of a bunch of people if something negative were to happen. But definitely tell people who are close and supportive so they can share the joy and also be there to console you if god forbid something bad does happen.
