Does anyone know if wondfo pregnancy test strips ever get daker than the control line? I know other test like frer and such can pull dye from the control line when your levels get super high. But what about wondfos? Mine have been about equal to the control line for 3 days and don't seem to want to get any darker. I've had 4 chemical pregnancies so I'm an obsessive tester I can't help it😓
