This is my first month Using OPK’s and I’ve logged them in premom and it’s so helpful!just wanted to recommend the Easy@home ovulation sticks from Amazon, they’re not expensive and it’s a box of about 25, you can download the Premom app and photograph your opk everyday (or twice a day in your fertile week) and it works out how fertile you are and plots them on a graph for you to see how your LH ramps up, then you get a peak (where the test line is darker than the control) It’s so easy to track with these tests. That’s what I’ve done this month![]()
