Vvf line for about a week.

Jessica • Mon, Mar 21

I have been getting vvf lines for about a week now. It's even gotten to the point where I've had one negative. I've tried digital but they show up negative also. I have tested in the morning, in the evening after holding it, everything. The lines do not seem to get any darker. I've taken idk how many tests. Anyone else had this problem?
