OP I think the thing to do is have a chat with your DH, reminding him why you didn't want the news to be shared yet.
There is a vicious circle with miscarriage that because people don't talk about it very much, other people, especially those who haven't gone through a pregnancy, have no idea how common it is, so assume that early pregnancy equals baby. Your DH should have done enough reading or listening to know better by now.
Telling people early is a very personal choice. Different people need and want very different levels of support and involvement. What matters here is whether you and DH would want immediate support from anyone outside your relationship if anything went wrong. The more private person's wishes have to trump the other person's, at this stage.
There's nothing stopping the less private person from seeking wider support later, if something did go wrong.
There is also nothing stopping you or anyone from talking about a miscarriage afterwards, perhaps long afterwards, when they are ready to, with the people they choose.
That is a way of letting people know this happens, that is relevant to the feelings of the person concerned. There is absolutely no obligation on you or anyone, to set yourself up as some sort of public information case study, at the time of your pregnancy.
