Answer: For breastfeeding mothers fertility decreases after childbirth.
More Info: Mothers who choose to breastfeed exclusively generally do not ovulate or have menstrual cycles during this time, many of whom use this knowledge in place of birth control. Researchers and family planners call this method of natural child spacing the lactational amenorrhea method (LAM).
Research indicates that a new mother’s chances of becoming pregnant with the LAM birth control method are less than two percent if she is exclusively breastfeeding without supplementation, her infant is under six months old, and has not had a menstrual cycle.
There are no hard-fast timeframes that a woman who is not breastfeeding may become pregnant after childbirth. A woman’s fertility is based upon her menstrual cycle, which can be erratic after giving birth. Many women who opt not to use birth control become pregnant within the first ninety days. Some doctors suggest waiting at least six to twelve weeks to give your body time to heal.
