Im NOT Pregnant? !!! ?

Christina • Praying our baby strength is enough this time.
So get this I took 8 pregnancy tests because I could not believe I am pregnant. Mostly from the 99 cents store. They were very faint at first but as days went on the second line grew darker. I knew I was pregnant beside all my symptoms i have all these positives. Based on my LMP I was only 3.5 weeks along on Sept 15th. On sept 19 I went to the doctor and I was so excited. I peed in a cup and waited 40 minutes to be called and the nurse of course checked my urine and she said that 3 test came back negative. WTH !! I told her I took 8 tests and she said well our tests are very very sensitive.....A positive is a positive. I understand that a positive negative is very very rare but 8? I have another appointment Sept 26th. I went home and took two more tests, First Response brand this time, and both positive. The next morning I used a Clear Blue Digital and another 99 cent store test.....that is 12 test that came back Positive......so I'm sure I'm pregnant. The photos below are after 1 minute of testing.... WhAt do you think?
