3 and half months of bliss with no AF... I have heard that it can return if you go more than 4 hours without a BF or expressing?? That seemed true enough with me...
If that is true then that explains why I have AF 7 weeks after giving birth, my DD has been sleeping through every night for the past week, she sleeps 6-9 hours overnight, not that I mind and if that means I get AF then its a sacrifice I'm willing to make for sleep.
