Pregnancy test

Hey y’all.

Not looking for any negative comments. So my period is a week late. I took two blue due pregnancy tests they came back positive. Then I took 5 pink dye and they all came back positive. Lines were very faint but they were there. I then ordered a bulk of them off amazon and they got here Sunday. I took one right when they arrived and negative. I took a few more. Negative. I feel like I see two lines on one the amazon ones. Then went and got two more pink dye and negative. I called my dr today and she wanted labs done. Just got a call saying the results came back as negative. I know that the blood test is the most accurate but how could that be ? 7 maybe 8 positive and blood test is negative? I mean if I’m not pregnant that’s fine I’m just so confused and concerned. No signs of period. I’ll attach all my tests. Thanks!

Edit to add she said my HCG was less than 1 which means negative.

I also asked about chemical pregnancy or miscarriage and she told me no. It would have shown in my blood.
