Will the tube I bought work?
If the tube is a 700x35 and your tire is a 700x37, it'll work fine. At that size, the 2mm nominal size difference won't matter at all. In fact, different vendor's tires in that range of size that have the same numbers on the sidewall probably differ in size more than 2mm.
