Malaysian work permit holders

[Hilluk]

Hi, not sure the correct place to ask. I apologize first if I have posted in the wrong place.

I would like to ask all those experienced people here. Me and my girlfriend are Malaysian working in singapore and holding WP.

However I think my girlfriend is pregnant, so would like to ask is it possible for my gf to continue work in Singapore while pregnant?? Getting married is a soon to be thing even before this news come to us but now the complications is the condition to continue work in singapore.

Does anyone have the similar situation as me? What are the procedure or document need to prolong my gf’s working period in singapore before giving birth?
Will her wp get revoked?? As i saw a rule, WP will be sent back or cancelled unless married to a Singaporean or PR approved by MOM.

Would appreciate any form of answer, advice or guidances
