Will my supply go down?

My newborn is 5 days old and breastfeeding at night has become very difficult and has been causing me a lot of stress because he cluster feeds at night. I was wondering if I pumped throughout the day and also breastfed and just feed him what I pumped at night if that would make my supply go down?
