My doctor always told me that no question is too silly. If I had a concern, he would address it. Those quick, sharp pains are a side effect of pregnancy in the later months. They typically go away as fast as they come on, but if you're still having pain in the area, ask your doctor. That's what they're there for. The things you would worry about are if the baby isn't moving like he was before, leaking of fluids, bleeding, or severe swelling in the hands or face. Things your doctor has probably (I hope) already told you. Before you know it you'll be sitting in the hospital room holding your beautiful new baby! Time passes quickly, so take lots of pictures... good luck!
