All of you mommies, I have a question about pg tests?

I have been ttc for almost two years, and this month I have all kinds of symptoms, well I tested 12DPO and got a very very faint line with the internet cheap POAS test, well last night went to walmart, and got an EPT, took one last night it was neg., this morning I took an EPT and an internet POAS, and the EPT again was neg. and the internet one had the same faint line, what do you think? Is it neg. or pos? I'm going to go today for bloodwork, but kind of wanted to prepare myself on what I'd here them say. Thank you so much for answering!
