Has anyone ever gotten an evap line on a wondfo pregnancy test?

I'm asking because AF was supposed to be here yesterday (friday) but Wednesday i thought I had started my period early. It was red and then quickly went to brown and was gone Thursday. And then Friday came and nothing. Then now today Saturday I took a wondfo pregnancy test and I've taken plenty of them and never got an evap line and there's two lines on my test it's not solid but a definite line is there. Even DH seen it. BUT after taking it I started lightly bleeding. Haven't filled an entire tampon today and usually the first 3 days of AF is so heavy I have to change a tampon every 1-2 hours. Any advice ladies?
