Hi, ladies! This is my first time using an OPK. I decided to go ahead and try one tonight as AF is late according to all 7 of my apps. I have a pretty irregular cycle (anywhere from 38-60 days), so I’m trying out different apps to see which one is most accurate for me. Anyway, from what I understand, my OPK is negative, but I’d like to know what others’ tests looked like when they got an LH surge before AF showed up. I’m hoping this is indicating that AF is coming soon as I’m anxious to try again! I’ve tested for HCG several times and gotten all stark white negatives.
