I'm so sorry Jen. And I'm sorry I haven't been around much to offer you some support. I had a crazy busy week.
I don't know much about FF, since I don't use it myself, but it seems to be helpful to many people and I am sure it's a good thing many times. The reason I don't use it is simply because I know that for me personally, the less I have to obsess about, the better. If your doctor, like you suggested, is willing to in some other way test if you O'd or not, try it out for a cycle and see if you like it better.
That said, I would also like to point out that FF is software. It just does what it does according to how it has been programmed. Your body is unique, and like Shelly and Michele said, you may very well have O'd, no matter what FF says.
I'm thinking of you and sending you all the positive thoughts I have. Take care of yourself Sweetie

. Let me know if there's anything I can do.
