I have started a business .. expected turnover is not more than one lakh rs per month..do I have to file gstr1 everymonth ? or quarterly?

if I am filing on quarterly basis, should I file gstr3b also quarterly ? and liabilities also quarterly?

if I want to file monthly can I do it ?

and I have changed the filing period from quarterly to monthly and monthly to quarterly again ... can I change it to monthly again... this is my first filing, I have not filed any returns..
