TMI leaking

Ali

FTM here, I’m 33 weeks pregnant and recently took out my nipple piercings that I had for almost 5 years. As of late when I take a shower I will look down and see around the holes (or what’s left of them) white stuff. The white stuff isn’t much but it has no smell and it doesn’t necessarily leak but if I press on it the “liquid” will sort of come out. This might be a dumb question but is that most likely left over gunk from the nipple ring or colostrum? Thanks in advance!
