Mommies need advice I'm a bigger woman just had a c section 17 days ago now my Incision site is very red sensitive and warm to the touch having severe pain by the incision with a little yellowish discharge I'm pretty sure it's infected ( this is my second c section didn't have an issue with my first one) I want to call my dr but I hate calling after hours ugh and I've had 4 hours of sleep in 2 days because of pain and my son gets up every two hours to eat... Should I call my dr tonight or wait until the morning
