Okay so heres the question......Does the result lines on OPKs get darker when getting closer to the day of ovulation? Reason asking is because I have been using easyclear blueplan OPKs....the lines have been very faint in color (including the test line), to the point where it was hard to tell if I was o'n or not. Well I've been switching up and using the answer ones too. When using the easyclear, it always showed two lines, but the answer ones only showed the test line. Well last night when i tested using the easyclear the results looked exactly alike so i wanted to double check with the answer ones. So i did and now im getting two lines with the answer one which has not happened before. The lines were not the same color

but they were there. Any ideas as to what is going on there??????
