I'm waiting on a check from my bank would it come sooner than 5-7 business days?

It's usually 3-5

The mail should only take 3-4 days, however the processing can take longer.

It easily could happen but normally it is much faster. It could get slowed in processing or in the mail or both. The day you really get worried about it is usually the day it will come.
