Bye-Bye, Menstrual Cramps
Sooner or later after childbirth and breastfeeding, your menstrual cycle will resume. But here's a welcome side effect: You may have fewer bothersome cramps. Some women even find that menstrual pain ceases altogether after pregnancy and childbirth. This pain reduction is a well-known phenomenon, but no one knows for sure why it occurs. One theory is that childbirth eliminates some of the prostaglandin receptor sites in the uterus. Prostaglandins, hormones that direct the uterus to contract during labor, also play a role in monthly menstrual pain. The upshot? Fewer pain-receptor sites, fewer cramps.
