Well, most of my cycles have been 28-29 days and today I am on cycle day 30. Geez,I keep checking like every 15 minutes to make sure it hasnt shown. I don't chart temps....just cm and BD so I have no idea when I ovulated for sure but it was either cycle day 14 or 15. FF said day 15 and I had watery those two days so I hope it was right.
I'm crazy stressed that AF is going to arrive...I do want this to be the month!! I'm going to test tomorrow morning....getting through this day is torture!!!
One of my friends (who is a nurse) didn't get her BFP until 2 days late! Don't count yourself out yet! I understand your frustration totally though!
