I have two bankruptcy two times before can i do it ?

There is no limit to the number of times you can file bankruptcy.  There are, however, limits on when you can receive a discharge of debts in bankruptcy depending on how long it has been since your last case filing, which chapter it was, and other factors. For a complete breakdown of the timelines see https://www.bklaw.com/bankruptcy-blog/2012/11/time-between-filing-bankruptcy/
