Good for you!!! - do not cut it.
You will be surprised, maybe even worried, how much the deer will take it down once it goes dormant, which should be about any day now.
In the spring, make sure you mow after the influx of weeds come to a head, (Late may) - but before they seed out - this will leave your clover in GREAT shape for the summer. Depending on how much moisture you get, you may have to mow 2 or 3 times next year.
I like to NEVER cut it after Labor day - if you can leave 6-8" for the winter - thats what you want - to supply over 1000 lb/acre of forage in the fall and winter - if the snows not too deep.
Sounds like you did great.
