Please pray for me

Hello all, I took 4 preg tests on Monday and all showed faint lines. On Tuesday and Wednesday (today), I took a test each and there is a faint line on both of them except that the lines are getting lighter instead of darker. My bbt is also going down. I'm worried that my BFP is going to turn into a BFN. TTC# 1 and actively trying for over a year. Please pray for me :)
