Hi there,
I used the cbfm when I fell pregnant with my ds. This is my 4th cycle using it ttc this time too. Each time I've used it I've been high from cd11-13 and peaked on cd14 & 15. I've a 27 /28 day cycle. This month it asked my for sticks on cd6 (never has done this early before) and I was high from cd8 and still am high on cd12. That's 5 days.
I understand that it can give lots of high days when you first use it but to dramatically change when I've used it so much is very strange. Anyone any experience of this? Thanks ladies!
