Exit in Macau twice.

Hi! i am planning to exit again in Macau for the second time around? Will that be a problem? Actually I am waiting for my dependant Q since my husband is her working in Hong Kong.

I arrived at the HK last august 14, so i was given until august 28 visa, but my aunt and i went to macau because she wanted to go there so I accompanied her. So my entry permit was extended up to September 1, now my question is can i Exit again in Macau for another extension for stay here in Hong Kong? Thanks!
