Pimple on labia?

Today I noticed a small white lump on my labia near the front of my vulva that looked like a small pimple. It didn't hurt or anything but when I pressed it to get a closer look it literally popped like a small pimple would. I cleaned it and googled it; it says it's most likely from shaving? Idk I've literally never seen anything like it. Wtf is it..?
