Okay I am so far from an expert on the ovulation strips. I do know that the control line and second line have to be the same color in order for a positive. Is it like a pregnancy test though? (as far as progression of line)? for the last few days my lines have been really light and today it is much darker. Does that mean I am almost ready for ovulation? I posted a pic of the strip and could use any help possible. My clomid calculator said ovulation would take place from 5/1 to 5/6. Thanks ladies, I owe you!
