oil-like discharge from breast

Ashley
Hey guys! 
So last night I was in bed and I noticed that my boob felt weird. When I touched it there was an oily substance on my boob. Almost like someone dumped baby oil all over it. There was a lot of it and it stained my bra. 
I didn't physically see anything coming out of my nipple. 
I'm concerned/freaked out. 
When I googled what it could it said that it was common after breastfeeding but I've never had a child/breastfed. 
Any ideas ladies?
