I'm 11 days pp from a vaginal birth. I was cut so I have stitches in. I've been feeling normal bleeding has almost stopped. I do have a kidney infection. I'm taking anabiotic's for it. Anyways today I started having pressure in my butt when I sneeze or cough or sit down. Do y'all think this is normal? Or should I call my doctor tomorrow?
