Oversupply gone at 10 weeks

I realize I had an abundance of riches that I squandered but I didn’t build up a stash while I had an oversupply. I work from home so didn’t have a goal post I needed to meet. But now I realize there will be times when I need to be away and I won’t be prepared. And what do you know but today pumping yielded little results. I know that my body is regulating to what baby needs now so the surplus is gone.. is there a way though to get it back up a bit so I can build up a stash? Has anyone else had an oversupply regulate and then increased again w efforts?
