Would it be wrong to keep my pregnancy a secret until 7 months?

I know this seems a bit extreme, but hear me out, I've had three miscarriages, and the last one we had just announced it. Then a month later had to tell everyone we lost the baby. And while I'd love to share the news I don't want to tell until we are much much further out of fear that I'll lose the baby. We thought we were in the safe zone, I was in my second trimester, so I'm very scared that'll happen again and since it'll be getting colder I can hide a bump much easier.
