I've been bf for 16 months and only got my AF back last month for the first time (two years to the day that i had my last period - so weird haha!). It was a fairly regular one, cramping, nothing out of the ordinary from what I remember and lasted about 5-6 days. My previous cycles were about 28-30 days. How long does it take for a cycle to become regular again once your AF starts again? I only ask because it's now been over 5 weeks and nothing. I had minor cramping on one day about a week and a half ago and I expected it to come but nothing. I've taken a pregnancy test (God help me) but it was negative (phew!). Not sure what to make of this?? Any info ladies???
