Shooting pains in uterus while breastfeeding

Monica • Baby boy born 8/7/18. Baby girl born 3/9/16. Learning so much about life and love being their mama.

Does anyone have experience with this? It hurts so bad sometimes that I yelp. It's not all the time, but will just happen randomly. It's always on the left side. Sometimes it almost even feels like an ovary, but I guess I wouldn't know for sure. It's right around the front hip bone area. My son was born August 7th by c section.
