I was on the pill stopped on sunday, i have stomach cramps and constipation, is that relates.

Constipation: Constipation inherently causes abdominal and pelvic cramps (usually worse right behind the uterus and on the left lower quadrant). Stopping the pill most likely was just coincendtal and has nothing to do with it. Treat the constipation and your symptoms should resolve. Drink plenty of water, avoid foods that can contribute to constipation (meats, cheeses, etc), and use laxatives if necessary.
