Anyone have something similar?

Has anyone had a faint positive that has stayed faint for a 5 days? I have taken I done even know how many pregnancy tests this week and most of them have all had the faintest of lines. I had a miscarriage on new years eve and this is our first month ttc. I am not very hopeful that I'm pregnant. I'm guessing it's a chemical. I had blood work done yesterday and I will have another draw tomorrow. But I wont know the results until Monday. I'm stressed out. I'm trying to hope for the best. But when I was pregnant both times before, after a day or so the line always got darker.( they were both boys, 1 living, 1 angel baby) I even feel like I'm getting ready to start my period. Idk if my mind is playing tricks on me or what. I just want to cry.

Has anybody been through this? Has anyone had faint positives for a week and still have a successful pregnancy? Please help a girl out before I break down!
