Hi Anne-Marie,
I used to get pins & needles in my hands and feet when pregnant, not sure if thats relevant to you? Maybe you could ask one of the midwives at the hospital about it?
In my experience, midwives are often more willing to answer questions than the doctors. You could ring the hospital and ask for a midwife. I have often called with questions when pregnant and they were very helpful.
Hopefully Tracy, the birth expert, can give you some pointers about it too.
Best of luck.
