Nipple discharge after removing piercing!

So I took out my nipple piercing about 4 weeks ago, the holes have pretty much closed up fully now. I squeezed my nipple just to check if the sensitivity was the same as my other and I ended up seeing some cloudy white/ pale yellow discharge come out of my actual nipple in the center.. I’m worried that it’s caused an infection did anyone else experience this after removing their nipple piercing? And what do I do 🤷🏽‍♀️
