2 month old sleeping longer, does milk go down?

Im a first time mom and have been ebf my baby boy since birth. he would wake up the occasional 2-3 hours to feed at night and it was exhausting! About a week ago he started sleeping 5-6 hours at night before waking up for his first feed, and god do I feel well rested now! Im soo happy to be getting a good amount of sleep. I do wake up with engorged boobs sometimes, so I’ll get up to pump sometimes, not all the time. Since I’m not breastfeeding him every 2-3 hours now at night, will my milk supply go down? Should I be pumping every 2 hours? Or am I okay to sleep through 5/6 hours without pumping? Need some help!
