Nipple Piercings

Hello everyone. I have nipple piercings, I got them pierced a year ago. I’m 35 weeks FTM, and today I started leaking colostrum. However, I have had crusties and puss like substances coming out of them on and off for my whole third trimester. I’m wondering, how do you know they’re fully healed? Do I need to take them out now? Is there any danger to the baby? Please help!! I was planning on taking them out when I went into labor but now I’m second guessing.
