Lost membrane to my pump

Elizabeth 💙👶🏽🌻🌱🌹

So I'll make my story short but in desperate need of advice. I breast fed my son at 530 from right breast n went to work at 7p. I went to go pump at 10 realizing that I left the membrane to the pump. I got off work at 11 p, rushed home to pump. The membrane is nowhere to be found. My son is sleeping 😫😫😫 my breast dont feel full but I'm scared to loose my supply. My LO typically does wake up around 2ish am to feed. Will I loose my supply!!!!
