Help!

Ladies, I found out this week that I am pregnant, I have had my bloodwork done and I have scheduled my doctors appointment. I'm very early so it's not until June 3rd. I was pregnant once before and it ended in miscarriage, I took a test the past 2 days and also one today, the one today is lighter than the one from yesterday but definitely still there, it's about the same color as the one I took on Thursday. I am so worried it's another miscarriage, with my last miscarriage though my lines never got this dark. I know I shouldn't stress about it a line is a line, but how do you ladies cope with the fear of miscarriage?
