Strange cramping

Ok, my fertile window isn't until the 26th, but for the last few days I have been cramping on both of my sides. They switch from side to side and are in farther on my stomach area then where my normal cramps are. It's not gas or anything like my mom thought. I've had them for 2-3 days and they hurt pretty bad. They aren't like period/ovulation cramps though. Does Anyone have any thoughts or ideas on what they could be or how to help them? Please and thank you! 😊
