breastfeeding = smelly vagina

so, ever since giving birth i’ve noticed my vagina smells...different. it’s not a foul odor, and i have no infection, but both my discharge and smell is different. it’s a little more musty, whereas before i couldn’t even smell it at all.

apparently, this can happen due to low estrogen levels caused my breastfeeding. so, is it true? did anyone else notice this whole BF? did your vagina “odor” go back to normal once you stopped? i know this is a random, but it’s been killing me. no infection, no problems, just a kind of off smell.
