:wave: sophabulous,
The line should get darker as you get closer to O'ing, it's not regarded as a positive until it's the same as or darker than the control line. I know there are some girls who never get a positive with OPK's the line is always lighter. Do you know when you normally would be ovulating, are you still a few days out from that? That may explain the faint line.
Hope thats helped a little, let us know how it goes and if the line gets darker.
