When to get help

Consult your doctor
- Vaginal bleeding
- Severe vomiting: if you are throwing up so badly that you cannot keep any food or drinks down
See your doctor immediately
- Abdominal pain
How big is your baby?
About 2mm long. NHS compares it to a poppy seed.
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.
