Should I get this checked out?

I'm only 17, but i've been doing self breast examinations since i was 13. today i noticed some discharge coming from my areola. not the nipple itself, but maybe 1/2-1 centimeter away. it's mostly clear with a little yellow tint and only comes out when i squeeze my nipple (relatively gently). is this normal? i can't find anything online about discharge from my areola, only nipple discharge, but i don't want to go to the doctor if i don't have to. 
there is a history of family breast cancer but a few generations before me. my mom found a lump in her breast when she was 28ish but it was benign.
