My hpt test, is it normal?

Lovely • IG: Plentifully.day TTC #4. Sept 2014 tubal reversal. Feb 2016 HSG: blocked tubes. May 2016 IVF: failed. Aug 2016 BFP turned to 4th loss

I took two this morning. The thicker one was bought at the dollar store (ucheck brand) the thinner one was bought on eBay

But one has a faint line and one doesn't, same thing yesterday, what does it mean??? Which do I believe?
