I need help. TMI

I'm ttc #1. I'm 4 days late. Ive taken two test, 48 hours apart, both bfp. The last one I took was this morning and now I have this. I'm taking another test on Friday and Saturday before I go to the doctor. But this is worrying me, I can't sleep. Ive read that it can be normal but I'm panicking. I'm so so scared. I don't think it's af because my periods have never been  this color. It's not getting any heavier and I need opinions. Thanks ladies.
