Frequently Asked Questions
A full-term pregnancy is between 39 and 40 weeks. Babies born between 37-38 weeks are considered early term, and those born after 42 weeks are considered post-term. Your healthcare provider will monitor you closely if you go past your due date.
The first trimester is weeks 1-13 (major organ formation), the second trimester is weeks 14-27 (rapid growth, you may feel baby move), and the third trimester is weeks 28-40+ (baby gains weight and prepares for birth).
Most first-time mums feel their baby move between 18-22 weeks. If you've been pregnant before, you may feel movement as early as 16 weeks. These first movements are called "quickening" and feel like flutters or bubbles.
Ideally before 12 weeks. In the public sector, register at your nearest clinic as soon as you know you're pregnant. For private care, book your first appointment with a gynaecologist around 6-8 weeks.
