Cramping 3 days in a row period isn't due till march 25 it's it ovulation pains or implantation cramping?

Mittelschmerz pain: Mittelschmerz pain or ovulatory cramping occurs 14 days before next period so you're in the right time frame. Check out http://www.mayoclinic.org/diseases-conditions/mittelschmerz/basics/definition/con-20025507 for more info. However, there are many other causes of abdominal/pelvic pain so if this doesn't go away, then go see your family doc.
