Help! How accurate are the EPT tests?

🎀S
I took one this morning and I got a very faint positive and I'm not sure if it's real or not then I took a first response but it's the curved one and I see a faint line too but for that I didn't use my morning pee I just took it now so I feel like it may be a dent ☹️  it's also five days before my period is supposed to start
