Pregnant & Anxiety

I am 5 weeks pregnant and my first OB/GYN appointment is not until the 24th of this month. I had a MC about 3 months ago and after that I have had the worst anxiety. I over think situations, I make myself think I have a tumor cause of my tension headaches... I just think the worst. Before finding out I was pregnant my doctor was going to prescribe me medication but I told her to hold off on it because I wanted to get better by myself.

During the week I found out I was pregnant my anxiety was not there anymore. But the last couple of days it has returned. I am scared of having another MC. I'm scared that my health might be an issue.. high cholesterol. I just want everything to go well. I want my baby to be healthy and I want to be healthy for my baby. There are times that are good and times that I just don't know what to do.

Any tips on how to deal with anxiety while being pregnant?
