Does an immature watermelon have stickers?

I have a vine that came up voluntarily and looks like a watermelon vine. It has produced small fruits from yellow flowers that look like watermelons except they're covered with stickers. Is this a watermelon or a thorny weed?

Answers:
i have never seen a watermelon with any kind of stickers. I think you might have some thing else growing.
