When to get help
HealthHub’s signs to act on, from 13 to 24 weeks:
Tell your doctor
- Vaginal discharge: if there is an excessively large amount or if it changes in texture, colour and smell
See your doctor immediately
- Vaginal bleeding
How big is your baby?
About 15.3cm long, head to bottom. NHS compares it to a beef tomato.
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.
