Pls share when did your milk supply dip? And how fast it took for the milk supply stop?

I also have hard time pumping at work now. Only able to pump during my lunch time .. And end work .. I will pump in the morning at 7 plus followed by my lunch time 12plus then end work 530. Remaining will be twice at night so I hope my milk supply won't drop so much even though it is now. Lo Alrdy 1year old but I wish to continue till she is 2
