What is considered a healthy, typical amount of time after childbirth for a woman to ovulate?

Depends. Ovulation after giving birth is different for every woman. On average, it occurs around 7 weeks after birth but can really happen any time from 4-11 weeks. This is also affected by breastfeeding as this prolongs ovulation. Women who are sexually active and do not desire pregnancy right away should be on some sort of birth control. Discuss your contraceptive options with your doctor.
Depends . That time can vary and will be affected by whether or not she is breastfeeding. Some women may go 6 months or more if they are breastfeeding exclusively. Women who are not have the potential to ovulate within 4 weeks. If this question is related to contraception do not leave that up to chance and address with doctor the different options.
