I AM CURRENTLY 29 WEEKS PREGNANT AND FOR THE LAST

i AM CURRENTLY 29 WEEKS PREGNANT AND FOR THE LAST WEEK OR SO (ONLY A HAND FUL OF TIMES) WHEN i AM WALKING I WILL FEEL A WEIRD AND UNCOMFORTABLE SENSATION FROM WHAT I THINK IS MY UTERUS TO MY VAGINA. I WOULDN'T CALL IT PAINFUL BUT SHOCKING ENOUGH TO STOP ME IN MY STEPS. ITS ALMOST LIKE MY BABY'S HEAD IS PUSHING HER WAY OUT. I KNOW I AM NOT IN LABOR THOUGH
