I highly doubt you have a BCC, probably a BCI especially if you got it from a pet store. I'd say 99.9% of the ones sold at the chain stores are the mass imported and sold BCI hatchlings. They aren't really THAT small when they are born length wise. I'm learning this stuff too but I also already have a BP and from my experience with her plus from what I've read about boas they can top 4 feet at the end of the year. They'll get MUCH bigger around also. Just feed appropriately sized prey once a week and let nature take its course.
