Your Baby During the First Trimester
Congratulations, you’re pregnant! The first trimester is an exciting time as your body gets busy building a baby. The symptoms are kicking in, and you might be feeling a rollercoaster of emotions. Being informed about what is happening in your body can be super helpful.
Here is a handy guide on how your baby grows during the first trimester.
How long is the first trimester?
The first trimester begins on the first day of your last period and lasts for 12 weeks. During this time your baby is working very hard and grows from the size of a poppy seed to as big a lime by week 12!
Here are a few of the amazing highlights happening in your body
At 6 weeks, your baby’s bones grow and arms, legs, hands, and feet begin to form. By the end of this week, your baby will have tripled in size. Your baby’s heart finds its rhythm. At this point if you choose to have an early pregnancy scan, you would be able to see your baby’s fluttering heartbeat.
· Baby’s organs
At week 8, your baby’s intestines begin to form. At week 10, your baby’s kidneys start to produce urine! By the end of week 12 most organs such as kidneys, genitals, heart and lungs have formed.
Baby’s facial features
At 8 weeks, your baby's ears and eyes begin to develop. The upper lip and nose have formed. By week 12 your baby’s face is distinct and their eyelids and ears are fully formed. At this stage you can see tiny details on your scan such as baby’s nose!
Although you won’t be able to feel it just yet, at 8 weeks your baby’s brain can make their limbs wiggle. By week 10 your baby’s teeny toes and fingers become visible (they will appear webbed). At 12 weeks your baby is stretching, kicking, and wiggling.
At around 9 weeks, your baby’s reproductive organs have formed which means you can now wonder whether there’s a little baby boy or a tiny baby girl growing inside you! Although it is too soon to visually confirm the sex of the baby, it is possible to learn this information via a blood test!
By the end of the first trimester your baby might start sucking their thumb and their face starts to fill out and become more baby-like.
The first trimester brings excitement along with some challenging aspects of pregnancy such as morning sickness, fatigue, frequent bathroom trips and anxiety.
If you want to meet baby early or seek reassurance about your early pregnancy, you can choose to have a private scan.
