Breastfeeding...

Im 25 wks & 2 days, and I just had a question... I plan to breastfeed, and I had my nipples pierced for years amd took them out about 3-4 months prior to conceiving, and theres Still white stuff that I can squeeze out of the holes. (Pretty gross i know) i googled it and it said that its just what your body produces when theres an open hole in your skin, but I dont want that stuff getting in my daughter milk?! T might make her sick? idk why they havent healed some ppl tell me they never will? I wash them and wipe them down w peroxide after every shower... Any advice? Lol😩
