Period.

• I got my period a few month after my oldest son Mica was born. Then it was another few months before I had another one. With Isaak I didn't get a single period until he was 5 or 6 months old.
• Breastfeeding causes hormonal changes leading to the lack of menstruation, or to irregular bleeding.
  
• Nursing and getting or not getting a period varies from woman to woman.
  
• Birth control can tamper with your cycle as well. Talk to your OB doctor about what birth control pills to go on while nursing.
