Cheap amazon pregnancy test

Chelsea

I am 14dpo I got my positive Friday 1/18 I took an amazon cheapie test and a vvfl showed up so I went out and bought a First response second like popped up clear as day. I’m a testing freak because I like to see the line get darker however these cheap amazon test still give me very faint lines like pictures below. That was taken this morning with first morning urine. It’s frustrating and worrisome I had a miscarriage March of 2018
