Does the anxiety ever go away

I’ve had a few losses and one healthy pregnancy.. I’m pregnant again and I can’t seem to shake the anxiety.. I feel great after every appointment but then a day or 2 later I’m back to worrying. I had my 12 week scan last Wednesday and everything went great . Baby had a heart rate of 167. We told family over the weekend and now I’m just hit with anxiety again worrying if everything is ok. I just found out that I’m anemic and have started iron pills .. from what I’ve read that’s more concerning for me than the baby .
