AF returned at 6 mos. post partum, despite frequent feedings. Now I want to use NFP for birth control, but am not sure about temperature charting. As far as I understand, you're supposed to take your temperature after at least 5 hours of consecutive sleep (and at the same time every morning). Well, I never get 5 hours of sleep in a row. Does it work to chart BBT in such circumstances?
Thanks in advance for any advice.
