This month was my first time using OPKs as my so and I have been TTC for 6 months with no luck. I bought a 10 pack and tested every day in my projected fertile window and then some but never had a surge. Just wondering how likely it might be that I could have either A, ovulated early before ever testing, or B, should I have been testing twice a day, maybe I missed it? Charting my BBT hasn’t helped because I only started that this month as well so I don’t really have any trends. Anyways I guess I’m wondering what others peoples experiences have been?
