Sharp stabbing pain in my lady parts

This might be a stupid question but I'm a FTM (37 weeks on Monday) and all of a sudden the last few days I'm feeling these sharp stabbing pains in my lady bits when the babe moves low down in my pelvis. Anyone else experiencing this??? They don't last long but I have to brace myself. It's like she moves low in my pelvis where her head is and I feel the pain. Then it subsides, then she moves again and more stabbing pain. It's off and on and at times takes my breath away. What is this and is it normal?
