Hai sayang, from what I've heard, most mummies who serah diri at PC are advised to go in the morning so the team can plan everything properly for your delivery, especially if ada kondisi like GDM, they'll want to monitor you from early. A neighbour of mine serah diri sehari before her due date and she said the process was quite smooth, just make sure you've packed everything the night before so you're not rushing. Semoga dipermudahkan urusan you, and wishing you a safe and comfortable delivery soon!
