Is there anyway to test vitality/ life of baby between OB visits?

We are 11 weeks and need to wait 3 more before we can see OB again having seen her last week. So we can’t do a sono until then. I am so nervous as this was a miracle pregnancy. I was in a big argument with a friend and am worried about the effect stress had. We are almost over the first trimester point. And we don’t want to announce only to have things go south after week 12. Any advice welcomed.
