One breast dry the other not?

katerpies

The last few days I have not been pumping just having my LO suck directly from the breast. Today when I went to pump my left breast nothing came out. I left the pump on there for quite a while and still nothing came out. When my LO sucks on it seems like he is getting something. My Left breast has always produced more so it was suprising that nothing was coming out today. 

Is it possible for one breast to dry up?

Im sorry if this seems stupid Im a first time mom and I have no clue haha.
