My daughter is 14 months and still nursing 4 times a day (including once MOTN). We want to try for a second now so that they would be fairly close in age, but my luteal phase right now is only 8 days. I got my period back at 7 months pp, but my luteal phase hasn't lengthened at all since then. I've tried adding vitamin B6, but that hasn't seemed to help. The lack of research on vitex while breastfeeding has made me nervous to try that. Other than weaning, is there anything else that had worked for others to increase their LP?
