Stress before EVERY appointment?

Tomorrow I go in for my 16 week appointment and I swear I have the worst anxiety. Worse than my 12 week appointment. I don’t know if it’s because I stopped my progesterone at 14 weeks and I’m anxious or because I had a TB test and I’m anxious or if it’s because of my history of missed miscarriages. I just feel so much stress it’s making me feel sick.

I know for my son’s sake I need to calm down. There is no reason for me to think something is wrong. I just feel so paranoid.
