Aih, mama, I know this is worrying, but please go see your doctor or nurse asap, even if no blood or open wound yet, it's better to get it checked out properly, especially at this stage! A few of us went through stitches postpartum and sembelit can put pressure on the area, so it's really important to rule out any issues. The stretching feeling you're getting needs a professional eye, could be normal healing, could be something else, but only your doc can say for sure. Don't wait if the pain gets worse or if you notice discharge, okay? Take care of yourself, mama!
