Confused

I thought I would be in this group but idk what’s going on. Last week I took two tests two days apart both had faint line, went to the obgyn, the test was positive but the doctor said it took 1 minute past their regular time to determine if pregnant or not. A week later I took a test but the second line was very faint could barely see it. My period is 6 days late, no symptoms so idk..
