Ruined milk

I had about 300oz of breast milk in the deep freezer at my mom’s because her house has more space. It got unplugged at some point recently, possibly over Easter weekend and they just realized when they got a food delivery and went out to put stuff in the other freezer 😭 I still nurse 2+ times daily but my supply took a major hit bc I’m pregnant. Now I want to pump again but I don’t think I can. Im so fcking sad
