I’m confused

So I’ve been breastfeeding my daughter since she was born (she’s 23mnths old) and for some odd reason, tonight while in the shower I randomly thought of seeing if I can STILL easily squirt milk if I just squeezed my boob a little... and when I did it came out so quickly from my right side but when I tried my left NOTHING. I squeezed and squeezed numerous times and nothing would come out 😩

Does this mean our breastfeeding journey is coming to an end!?!?
