Don't worry about it.

As you lose weight, they'll probably get smaller - and if they don't, what are you going to do? Shave 'em off?

(FWIW, when I was your weight, in college playing football, I had 21 1/2" calves. They're only 19" now with me at about 200 lbs so I'm thinking yours will probably go down as you lose weight too.)
