9 weeks pregnant
At 9 weeks you are in the first trimester, and your baby measures about 2.3 cm from crown to rump and weighs about 2 g, roughly the length of a grape. All the major organs have started forming, and this is the week to settle your public maternity care model, since midwifery group practice and birth centre places go early.
Averages from standard growth tables; your scan gives your baby's own numbers.
Your baby at 9 weeks
All the major organs have started; the tail is gone. Now called a fetus: the tail has gone, fingers and toes are forming and the head is about half the total length.
How you might feel
Tiredness and nausea usually continue, and some people notice their waistband is already tighter from bloating rather than the baby.
Choose your care model. MGP and birth-centre places go early.
Call your maternity unit or GP today for bleeding, severe pain, or if you cannot keep fluids down. 13 HEALTH (13 43 25 84) in Queensland; 000 in an emergency.
