I've never really experienced cramps while having my period, or ever.. except the beginning of my labor. Now that I've given birth I've been having painful cramps today. It's been 17 days since my c-section.. Maybe it's my uterus healing?.. Maybe it's my period coming in? I'm not even sure. I've been bleeding since my labor, so I wouldn't be able to tell and I got the depo shot the last day I was in the hospital...
