D.S.
Call your doctor just to put your mind at ease. I had the same thing. I was given pitocin because my labor wasn't progressing. I dilated from 2 to 10 centimeters in 1 hour. After birth I felt like someone ripped my inside out for weeks. I was very very sore. It could be normal, but put your mind at ease and call the doc. Congratulations on your daughter!!
