Help please!

I just recently got off birth control after 5 years. I had my first normal period from March 15th to March 18th. Now, almost two weeks later, for the past 3 days I've had dull cramps on my right side, right beside my hipbone. It also makes my right leg a bit cramped. Has anyone else had this, and is it ovulation cramps? Glow says I just started my fertile window, so I'm not sure.
