Milk supply drying ?

I’m 10 months PP. I EBF. But my little wet diapers aren’t as they used to be only getting 4 big ones and 2 light ones a day. Pooping once a week still.

Not sure if my supply is drying up or not she seems to be able to drink off me still. She will not take formula so if I lose my supply don’t know what to do.
