Nipple piercings (TMI)

Hey ladies,

This is not fully pregnancy related but possibly others have experienced this..

I took out my nipple piercings around the start of my pregnancy and now every time I shower I notice white stuff where the holes used to be. I can squeeze it out and it’s kind of thick. I have no idea what it is or if I should be concerned, especially since I plan to breastfeed.

Has anyone had this before or know what it could be??
