 [ Symptoms ] i am 37 weeks pregnant what are the sharp vaginal pains that make it seem like my baby is stabbing me from the inside [ Disease ] probably sitting on a nerve typically one gets severe back pain if the baby is pressing on a nerve i would recommend calling a doctor is office any assistant can answer you can also call an emergency just to confirm if this something to worry about   they will bring you in if they are not sure i called once when i had numbing down my left arm   and when my son ate some plants i knew nothing about   they are very helpful
