Nipple discharge and hurting a lot

Hi I’m 19 years old, no babies, not pregnant either, but for a couple weeks now my nipples leaked clear/white fluid. It’s happened five times in the last couple of weeks. Also my nipples are so sore and sometimes hurt to even touch. Has this happened to anyone? Should I go get it checked out? I wasn’t as worried when it first happened but now they’re starting to hurt a lot and I’m not sure why.
