Weird supply


Hey mamas! So I feel like my milk supply is weird. My daughter is 7 weeks old, and there are days when my breasts are practically completely empty no matter what I do, and days when they become engorged and I'm leaking so much that my milk soaks my shirt almost entirely. I feed my baby as often as she needs, and sometimes she needs it for comfort too. And I'm trying to pump as well but when I do, the side I pump from (I try to save one side just in case she wakes up hungry while I'm pumping) becomes really empty and doesnt want to fill up. Could I be doing something wrong? I worry that shes not getting enough. Do I just need to increase my supply?
