Lime Green Discharge?

About a month or so ago I woke up with a pretty significant amount of very very bright, lime green, -what I guess is- discharge in my underwear. Wasn't smelly, but very sticky and somewhat hard. It almost looked like if you were to crush a green skittle (gross, I know😁.) After that morning, I haven't had any more of it again. I'm curious to know: has Anyone else ever experienced this? What could it be?
