I noticed a change in my cm a few days ago so thought I'd start using OPK's to see when I'm ovulating. Used these with my first and they worked just normal cheap line ones. My cm is still egg whitish but a bit more watery (tmi) so I haven't ovulated yet and the lines are still very faint. I'm just wondering if anyone can tell me how many tests they did before their opk read positive? I've just come off the pill 2 weeks ago and had no af and I also have polycystic ovaries so no idea a out my cycles. Do opks read negative with no second line at all then the closer you get to ovulation, the second line is faint then gradually gets darker (indicating ov?) Any help/advice appreciated! 😁
