Menstraul back?? Or concern

Chardonnay • 🌻25🌻 mommy of 3

Hey guys, I had got my menstrual back at 7weeks pp and bled for 6 days. A week went by and I started spotting again and now been spotting for 4 days. I've been having this sore feeling in my pelvis ever since I got my period back and it also bothers me when I walk. I breastfeed and is wondering if this is normal occurrence or should I call my doc??
