Does anyone suffer from this? When should you seek advice? I'm really struggling to walk, my niece suffered with this during her last pregnancy so when I described what I was feeling she thinks I might have the same. It feels like very strong pelvic pressure, like severe bruising standing and walking makes it feel worse. Alsmost like baby is going to drop out!
