Translate to Mandarin

Can you tell me how to say "Do I wash the dishes?" or "Is it my turn to wash the dishes?" in Mandarin?
I mostly speak Cantonese and I usually say 係咪我 洗碗Ah? I'm not sure if my Cantonese is good either.
I'm also unsure of the character for "Ah". Is it 啊 or 呀? Would it be 係咪我 洗碗啊?

If the Cantonese is wrong please correct it.
