Need help

I took the bottom test last night and after a few minutes I figured it was negative but after and hour I saw a line, I have never had these kind of hcg tests get a line after any amount of time if it was negative. So I took the top one a little while ago and I see a vvvvfl but the camera isn't picking it up in the photo. So I took a clear blue test and it was negative, I was told blue dye tests are not as accurate as red ones so early on. I'm 8 dpo plz help, I had a mmc in September and am praying this is my Rainbow baby.
