just a query about my 'ouch'

[LoveFlump]

yesterday I noticed short sharp pains on the right hand side of my stomach..i asked my OH's sister about them as shes just had a baby..she said it was the baby kicking..i took that as the answer, but later I got them on both sides..so unless im having a ninja baby in football boots, I dont think it can be that..ive had it again today..anyone else had that? Or know what it is?
