Weird cramps

saoirse
Hi,
I've been getting weird, sudden, painful cramps on my lower right stomach (few inches above my right leg.) It's been going on for maybe a week, week and a halfish. They are short lasting, only up to a minute or two, and come sudden with no warning. They can be really suttle or very painful to the point I have to sit down.
Should I be concerned about this? I have a dance competition next week that is very important to me, so I'd rather not have that postponed by something minor.
Background information: I am 16 years only and female. This is the first time this has happened. My mother gets regular kidney stones, of that connects, and there is a history of ibs and lactose intolerance in the family.
Thanks
