Pea size bump on cervix?

Brittany

I have an appointment with my OB next Friday but I have a hard bump the size of a pea on my cervix. It really creeped me out. I’ve been having a LOT of discharge recently on top of that and some cramping. I’m almost 11 months postpartum and nursing so I haven’t had a period since October of 2018. Anyone else have a lump like that and what was it?
