I recently took an OPK hoping for a positive as we are ttc. Well after a few minutes I got what I thought was a positive but now I'm not sure. The test line was two different colors. The bottom of the line was dark but the top of it was faided. It literally was a dark line with a faded pink Line ontop of it. Anyone else have this issue before?? It's was a cheapy dollar tree OPK so maybe that was the issue...
