Spotting while still breastfeeding

Lola

I’m almost 10 months postpartum and still breastfeeding, but I’ve been having bloody discharge or light spotting every once in a while. I know I will most likely not start my period again until I stop breastfeeding, but anything’s possible. Just curious if this is common.

My history: endometriosis, fibroids, uterine polyps, cervical polyps
