And every time I take a test I get this. I cant tell if it is an indent or a vvvvvvvvfl?

It's on every test I take. Not getting darker though. The darkest part is the edges. In person it seems to have a little color to it's especially the edges

I dont want to go to the doctor and it be nothing.

I am going bonkers. I am 3 whole weeks late and the only time I have EVER skipped a period in my life was when I was on the implant. We've been trying for 7 months now.
