Confused

So I am about a week overdue for my period. I took a test on Friday and I got two positives, but with very faint lines... Saturday morning I took a CB digital, and I got a "pregnant 1-2 weeks". Yesterday I went to the dr and left a urine sample. I got an email today from the dr's office and it said "negative -inconclusive" wth?! I took another digital test today and it also says pregnant.. Is it possible that it's still too early for the dr's test?? Now I'm confused and nervous as I don't want to be disappointed.. Help
