Just wondering if this has happened to anyone, but today while at the grocery store I felt a dull pain right above my left hip. I shook it off and a few minutes later it felt sharp like someone stabbed me, it maybe  lasted a few secs at most and went away. It hasn't happened before, nor since this afternoon. Baby seems to be fine, still kicky up a storm. I'm just a little nervous. I'm going into dr office tomorrow for the glucose test, so I'll ask then, just wanted some advice.
