I got my BFP on Thursday morning, but...

I keep feeling the need to take more tests! I absolutely can't help it. I took 4 tests on Thursday because I was so excited and surprised, then Friday I took another, and Saturday I took another, I've held off today because I know it's all in my head. My first appointment it tomorrow and I think I'll feel much better then, but until it's confirmed I just feel like it's not real. Has anyone else had this problem? I mean, false positives are rare, and I'm sure 6 different tests would not have shown false positives lol. Please someone ease my mind lol. Thanks ladies! Included are pics of my first 3 tests. All positive. One was even with diluted mid day urine.
