Are very heavy periods enough to soak through pads every 1 hour normal when breastfeeding a 1 year old?

Irregular periods following reduction of breastfeeding is very common. It reflects your body's efforts to recalibrate hormones back to normal levels. It can take up to 6 months to resume normal cycles. Unless you are trying to get pregnant, use a trusted method of birth control every time you have intercourse. If the irregularity persists past 6 months, see your Gynecologist.
