I have the same sharp pain in the same area which I know in my case is sciatica. Very painful. My guess is that since you're further along, the weight of the baby may be applying a lot of pressure on your sciatic nerve causing the pain. Hope you get the answers you need from your doctor. Take care. :)
Different Women have different symtoms - Maybe this kind of pain is usually because of what mentioned by Lacy but u shld definately see a doctor and discuss it with her.You do not have to worry much as the pain is not associated with the abdomen and yes do not take Stress!!!!Take rest.
well your body starts preparing for delivery from day one, weather its the blood flow increase or your hip spreading .... I'd say thats what it is
