I've been having lower abdomen aches, like PMS cramping for the last few days. This is the first time I'm experiencing this postpartum. I'm still breasfeeding my LO who is currently 10 months old. I mostly breastfeed during evenings, night, and early morning...since I work full time (I also pump at work 2-3 times a day). BTW, I follow NFP/FAM so there is no hormonal birth control to blame. And no, I'm not currently pregnant. My question is, is this cramping I'm feeling normal at 10 months postpartum? How long does it take for menstruation to return?
