It is probably newly a spasm that is commonplace. talk to you doctor though incase it is serious.
Cramps are usually cause by a lack of potassium. She should see her doctor for some blood work.
it could be a spasm because she have no pain but it could be mineral deficientcy a check up at your gp would put your mind at rest
