Question about Visit Pass

[tcl1987]

Hi, I'm a Malaysian and what happen to my case is like this:

This is my 2nd time entered to Singapore using visit pass and it will expire on 16 April. However, if i plan to visit my friend in JB on 2nd of April, can i re-enter to Singapore again for the 3rd time using normal visit pass which valid for 30 days? Or do i have to back to Malaysia for one month then only after that I'm able to enter to Singapore again?

Thanks for any help.
