Please look at these tests , scared

Taja • BFP May `14 had miscarriage 7/22/14. Got BFP 2/27/15, CP 3/6/15. Praying for rainbow baby
I had a miscarriage in July 2014, I just found out on Friday I am pregnant again , but I feel like these faint lines are not getting darker , I can't see the Dr. until Wednesday 😥 Is this a bad sign or am I stressing and freaking out for no reason. My SO says I'm freaking out & it'll be alright but I can't help but be skeptical. Please any advice would be helpful!
