Anyone else?!

Brooklyn
Ttc #2 here, however I'm still breastfeeding number 1! He will be a year in October and I was wondering if there are any other mothers who breastfeed and still get crampy? 
I have a regular cycle, and ovulation seems to be coming when it should maybe a little early. 
So if there is anyone else could you help me shed some light on why I'm crampy? 
Thank you ahead of time!
