Possibly Pregnant?

I am a little over a week late on my period. I took 3 different test. 1 last week that said no, i was anxious and realized it was too early to take one as i was late by 2 days. I took 2 today and 1 showed what appears to be positive. Saw a faint second line and the other said no. Has anyone experienced this before? Did it turn out you were pregnant or not? So confused.
