work permit and visitor visa in parallel ?

[adelaide4]

Hi,
    I've applied for both : work permit extension and visitor status.

I'm pregnant and as I'm really not sure of my open work permit extension approval, I also applied for visitor status.

1) Is it good to stay back as implied status of visitor if my work permit gets rejected or should i go back to my hometown ?

2) Can i wait until I know my visitor status ??

Please reply !!
