Can you get pregnant 4 weeks after having a baby?

It is unlikely but possible to become pregnant 4 weeks after having a baby, especially if you are not breastfeeding or using birth control. To reduce the risk of pregnancy during the postpartum period, it is important to wait until your menstrual period returns and to use a reliable method of contraception. Be sure to speak with your doctor about your contraceptive options and when it would be safe for you to resume sexual activity.
