I am wondering if someone can give me a bit of MN reassurance - I am 31.5 weeks, and have a big bump and baby (measuring at least 3 weeks ahead), and when I walk briskly I get a really sharp stabbing pain shooting right down into my vagina. Its sore enough to take my breath away. When I stop walking it goes away, and the baby is wiggling away happily. I am assuming its just because the baby is resting on a particular nerve or something, but I just wondered if anyone would be able to reassure me that I am not the only one experiencing this? Its not a contraction - my tummy stays soft, just a really sharp pain. If anyone has any thoughts they would be very much appreciated. Many thanks.
