I am on CD 19 and FF "thinks" I may have O'ed on CD 16, but I didn't get a +OPK until CD 17. I think I O'ed on CD17 based on OPK and cramps. Thoughts??
We should be covered as far as BD. WE BD'ed every day since CD 15 and EOD before that from CD 7-13
Re: Chart stalk
The book, Taking Charge of Your Fertility says that if you have a huge dip that is the day you ovulate. I think FF is correct.
