Forgot my flanges

💀

Ok so how screwed am I? I’m at work and I went to pump and I forgot my flanges. I tried hand expressing, but didn’t get much. Maybe an ounce? I probably would have gotten at least 3oz pumping. Maybe close to 4oz. It’s 6:30p and I’m scheduled til 11p. I usually leave late and don’t get home until midnight. Will this affect my supply a lot?
