Faint positive line help?

Okay before I go into details. I was on depo 1+ year this is my 2nd cycle off and yes I got my period back it's just VERY irregular so me and my DH basically just went at it like rabbits every other day. It's been about 4 weeks and still no AF. But I have breast tenderness, nausea, tiredness, and moodiness swings. Sooooo I took a clear blue (early easy) digital test it was a BFN I cracked it open just to see and there was a faint line that even my DH saw. Should I test again in a couple days get a diffrent test? Help please?
