See your doctor immediately
- Vaginal bleeding
How big is your baby?
About 12cm long. NHS compares it to a pomegranate.
Leave and Baby Bonus
Coming up from week 30: tell your employer about maternity leave. Give at least 4 weeks' notice before your leave starts. For leave from week 36, the default start, tell them by week 32.
Which baby scheme applies follows the actual birth date. Born before 1 April 2027: the Baby Bonus Scheme. Born on or after it: the SG Child Support Package.
