Postpartum Vaginal Soreness

Okay, so I'm 6 days postpartum and I've been feeling amazing. But today I felt like every muscle in my vagina is sore. It's weird. I honestly don't know how to describe it other then sore muscles but it's still different than normal sore muscles. I haven't felt much discomfort down there until today. Of course it was super sore and stuff the day I had my son, but today is just weird. I did tear. But just needed one stitch. Someone help a girl out. Explain this to me. Is it normal? Should I call my doctor?
