In general I would use Postpartum up until the period or 1-2 days before cramping starts. Then start Channel Flow, 3 capsules BID, prior to cramping. Use 2-3 capsules as needed during cramping every few hours, 3-6 times per day. If liver qi stagnation stop Postpartum during ovulation and add Woman’s Balance and or use Postpartum and Astra Essence to address kidney issues. Expect some results around 60 days, and 6-12 months before problem is cleared.
