Please help me, terrified

Emma

I’m sorry for the picture but is this something to be worried about at 21 weeks exactly? It’s Christmas <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> 1am and I’m terrified (had a missed miscarriage right before this pregnancy and I just started to really chill and enjoy my pregnancy). What should I do, what would you do?
