Small discolored spot near cloaca

So I recently got a ball python who is about 7 weeks old. Today I noticed that to the side of his cloaca, about where spurs would be, there's a little bit of discoloration (kind of yellowish) and a slight bump. It's really small, maybe half the size of a cooked grain of rice. I may be able to provide photos later but he's still pretty skittish so I'm trying to not stress him out too much. Because it's right next to the cloaca and I couldn't get a super good look at it, I feel like it may be normal but I want to make sure. He's on reptibark, has a uth with a thermostat, and temperature and humidity are normal (~60% humidity, high 70s on cool side and high 80s or 90 on warm side).

This is my first snake and I may be panicking but any info would be great.
