You could try it any time you like. By trying it too early, you'll find when is too early, and then next time you'll know.
When I was bottling, I'd try after 5 days, no problem. But normally it was not really there yet. But at least it was homebrew, right?
Go drink one now if you want. You got like 50 more, right? What's the big deal. If it's almost there, try again Saturday (if you can wait that long). If it's not, try again Saturday (if you can wait that long).
My point is, try it if you like. Understand it might not be ready. Do not judge it yet. But feel free to try it. After you've tried enough at 5 days bottled, you might be able to judge it at this point. But for now, it's all learning.
