Should we wait to announce?

At my dating scan, we discovered a subchronic hematoma. I have not had any bleeding so far, and pray it stays that way! We planned on announcing on social media when we find out the gender at 10 weeks...

My biggest worry right now is going into my 12 week ultrasound and not finding a heartbeat, or losing the baby after we post. My doctor didn’t seem concerned about it, but I may have overly googled and got myself worried!
