Anybody else have bad anxiety?

Maybe it’s because I had a miscarriage in July; but I literally worry about everything in this pregnancy. I have an anatomy scan on the 15th and I’ve been having anxiety attacks about it. I’ve had to take a break from this app because I read posts from other moms and my mind just goes into overdrive. Any tips on how to calm my mind? So far everything has looked fine with the baby, but I can’t seem to calm my mind down..
