All Negative OKP's
I've been using an OPK this month and so far I have not had a single positve test for my LH surge. I'm on cycle day 20. My CM was very much ontrack this week but no positive test. So I figure this means three things:
1. I havne't O'd yet. Seems a little late since AF is due on 9/29. She's been like clockwork for 4 months.
2. I'm not O'ing at all.
3. The test isn't strong enough to detect my LH surge.
What do you girls think? Any experience with this?
