Could i still be pregnant?

We do not have protected sex, sometimes he finishes me sometimes he doesn’t most of those sessions were multiple times a day. I took pregnancy tests a few days ago ( blue dye) faint limes showed and then it started showing horizontal lines when they should be vertical. I retested yesterday saw a faint line on both test but not strong my spouse says there is no lines. I usually get my period a week earlier than what Glow says. On the <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a>. App I am like 3 days late. Should I wait? Or?
