Clear blue vs dollar store test

Chanel🎀 • 20 years old🎉 expecting baby #1 due july 11th 🚼 engaged 💍👰🏾
So I bought The clear blue double pack pregnancy test used one on March 20 that one came up positive it's a very faint line then I had a bleeding for five days after took another test came up very faint again with a positive then just to be sure I bought a test from the dollar store that one came up negative I know the best thing to do is see a doctor but I was wondering which test is more trusted and why?
