Hi welcome to Healthcaremagic
If the pain is severe, associated with vomit or fever
, then you need to get USG of abdomen to rule out appendicitis
... also in some cases there are chances of ectopic pregnancy
which also may represent in the same way... But do not neglect the pain consult a gynecologist... At present a tab.Buscopan
may be helpful..
Hope I have answered your question..
