Thanks for posting your query.
The cramps could be due to either menses or bowel infection that is causing diarrhea
If diarrhea is persistent, get a complete blood count
and stool test
done to find the cause.
Take antispasmodic medications for pain relief.
For relief from loose stools, take probiotics.
Drink enough fluids/electrolyte solution to remain well hydrated.
