Could this be ovulation pains?

I just recently got off B/C after 5 years. I had my first regular period almost two weeks ago, so I was surprised when I got these dull cramps right beside my right hipbone. It also makes my right leg cramp up a bit too. It's been happening on and off for 3 days now about. Does that sound like ovulation cramps? According to this app, I just entered my fertile window yesterday.
