Plan for confinement

I am currently at week 12. My EDD is this year Dec. May I know when should I plan for confinement? Since both our parents are not around in Sg and I don't want to stay in confinement centre, I prefer to engage confinement nancy through agency. Any recommendations? And how much is the cost right now? And what are the things I need to ask while interviewing them? #pleasehelp #pregnancy #advicepls #confinement #confinementnanny
