Input please?

Has anyone tried the water test on a used pregnancy test? I thought i saw a vfl when i took it after y dried it had a line and i put water on the strip so it could wash the pee off and the stains. Also the evap if it was one and this stayed. It has color in person but again i can't trust it cause i saw it after. Anybody who's had experience with these Walmart cheapies that i am beginning to hate!
