This baby will be my 4th c section- I’m going to call my doctor but thought I’d ask here as well. Last night and this morning my stomach has been getting incredibly tight with each contraction ( I’ve been having contractions off and on for a week) however now with each contraction I’m having a really intense burning pain under my scar from previous c sections. Has anyone experienced this? Obviously this isn’t my first rodeo here but I’ve never experienced this burning with contractions.
