return of menstruation after breasfeeding

I have a four month old child. I was exlusively breast feeding until he was slightly before 3 months.  I had problems conceiving this child.  When should I have a cycle again?

My physician told me about 6 weeks after feedings are less than 4-5 a day.

It may vary with each woman, however, breast feeding is factly known to either slow down or completely stop (not forever of course :) ) the return of cycles. i nursed my son for two and a half years and didnt get a period, however a month after i stopped i got my af back! it doesnt mean i didnt release eggs however. i still have breats milk left and my son is four! a fren of mine nursed her baby every day until four months and didnt even get a af and found out she was preggo! it will more than likely return like lauraandbill2001 said if u slow donw on the nursing, especially at nite.
