Anxiety & stress TTC

I have recently had hormone testing with my Dr and I was expecting her to say everything was normal but that wasn’t the case my progesterone was abnormal ? i have a ultrasound and follow up appointment on the 12th but I think I’m going to go crazy by then. I’m only 22 and have never had any problems before. I will admit I was on depo for 4 years and the patch for a few months so I never knew I had irregular cycles until I began TTC. I’m freaking out and all I do all day and night is google what causes progesterone abnormalities, infertility and how to fix it and stress myself out. I know stress isn’t good for fertility but I seriously can’t help it. My fiancé and I want a baby so bad 😩. Anyone have any tips on how to calm down and not stress as much??
