EBF sleeping 7 hours, is that okay??

Silly question. But for my milk supply is it ok that I've gone 7 hours between feeds? My son is going to bed at 7p so I could easily pump before I go to bed. Should I? He's only 13 weeks but is over 13lb and has steadily gained weight/made dirty diapers. I'm just worried about my future milk supply
