Are these watermelons?

Are these watermelons or some kind of wild melon that's not eatable? I did not plant these...I discovered the vine growing on my property...We live in extreme southeast Louisiana...

Do you have picture of the leaves? Flowers, too....

They are not likely to be watermelons, at a glance, maybe cucumber, but maybe not. If someone planted them in the past they are likely a cross between several different varieties and even if they are edible they might not taste very good (I am assuming you picked these off a vine). Applestar is right without seeing leaves etc, it is hard to guess accurately. If it were me I would pull it up and throw it away as crosses in the squash, cucumber family often taste pretty bad.
