Random AF nipple discharge?

So yesterday night after I got out the shower and towel dried, I noticed after I put my shirt on that it was wet around my nipples. My boobs are really sore and tender and they have been for the last few days. anyways, I lifted my shirt and took a glance at my areola and it looked swollen (bot of them). I tried squeezing the nipple and more milky type of discharge came out. IDK what it is. The only time I got that was when I was well into my pregnancy but that was 3 years ago and I barely produced milk. I dont think I'm pregnant. AF isn't due until 3 days from now. I dont want to take a pregnancy test just yet because it's too early. Anyone else have this issue before?
