Did I ruin my milk supply??

Brittany

Baby girl falls asleep when latched On so I’ve been pumping and bottle feeding her. I’ve usually been able to pump 3.5-6 oz each session every 2-3 hours. However the past day and a half I’ve been sick so I only pumped like twice to relieve the discomfort but I had enough stock in the fridge to not have to worry about regularly doing it. Now I’m trying to pump regularly again and it seems like I’ve dried up or something. I’m only getting like 2-2.5 oz each time and it’s difficult to even get that. Did I ruin it by skipping that day? Or should I just keep trying to pump and it should restore?
