What should I do next?

So last Monday 11/20 I took an at home test and I could see a faint line

Then I called my regular dr to see if I could get a test there to confirm. I also called and scheduled an appointment with my Ogbyn but it’s not till dec 18th. When I went to my regular dr appointment that day they took a pee test and it came back negative. Then he decided he would do a blood test also came back negative.

Well I still haven’t start my period. At this point I’m 6 days late so I decided to take another test last night.

I couldn’t get a good picture but in person you can see it a little better it’s very faint!

Then this morning when I first got up I took the second one in the pack

Here is the two compared

What should I do now? I also have a scope scheduled for the 30th should i call and cancel? Help!
