10 weeks pp and I've been having mild pain on and off where my kookah entrance is like when I was recovering after birth and when I went to bathroom, I wiped and had a dime sized piece of mucus looking stuff that had a yellowish tint..can I be still shedding leftover mucus plug this late or what do you think it is? I'm kinda crampy now.
