ok um... when i get my period not only do i get the annoying but normal ache... but i also get stabbing pains in the lower abdomen. last night they woke me up and i couldnt get back to sleep. they're worse when i wake up in the morning. and i could be walking along and suddenly have a stabbing pain and have to keel over... anyone else get this? am i normal or is this not so great? are they wind-pains???
