3 faint positives all taken with in a week. Is it normal that the line was still faint?

I've taken 3 different test 2 blue 1 pink all came back with faint lines. All taken different days 2 with FMU. After a week should the line have gotten darker by now or is it normal for it to take it's time to show up clear on a PT.?
