Women typically ovulate 14 days before their period, but this can vary from 11–18 days depending on the length of your menstrual cycle.
A sperm enters the egg: they fuse to become an egg composed of a single cell.
The fertilized egg attaches to the wall of your uterus. This stage is called implantation.
The embryo’s round shape becomes elongated. It now looks like a tiny seahorse.
Baby’s heart begins to beat. But that tiny heart is still forming. For now, it looks like a small bump.
This week is marked by significant brain development.
Even if you don't feel it, the embryo is moving.
Arms and legs become longer and their elbows and knees, along with their wrists and ankles, become more defined.
The embryo's heart rate is around 170 beats per minute. It will slowly decrease as the months go by.
Week 11 marks an important milestone: the embryo has become a fetus!
Good news: at the end of this week, the risk of miscarriage drops considerably.
Baby tooth buds appear. Adult teeth will come later.
Baby can now make certain facial expressions like frowning and grimacing, and starts sucking their thumb.
Baby is beginning a period of accelerated growth. Their legs are starting to be longer than their arms.
Your baby is stronger and their kicks are more pronounced. Their movements are also better coordinated.
This is very important. The fat will help your baby stay warm after birth.
The sex can be identified. Ultrasound shows the penis or vulva and uterus.
Your baby is going through an important change: the areas of their brain dedicated to the five senses are forming.
Your baby is learning to move their body parts.
They also like playing with the umbilical cord.
Your baby already likes the taste of sugar! The sweeter the amniotic fluid, the more they drink.
Their eyelids are coming apart gradually. They’re becoming aware of light and darkness.
Real hair has started to replace your baby’s fine downy hair. Their fingernails are more distinct.
Your baby is beginning to recognize your voice, daylight, certain activities, and more.
From now until birth, your baby’s face won’t change very much!
Perhaps, since brainwaves associated with dreams have already been detected.
When they sense light or hear a sound, they turn their head in that direction.
Their nutrition is very important. They’ll get what they need from your diet.
Their vision is limited. They can see 20–30 cm in front of them.
Some babies are already head-down. They often stay in this position until delivery.
You can feel your baby wiggling and jerking their arms and legs.
They have the proportions of a newborn but will continue to grow and gain weight in next few weeks.
Their skin has turned from red to pink. Their fingernails have reached their fingertips.
Two important structures—your baby’s brain and immune system—have reached maturity.
Inhale, exhale . . . Your baby is practising! Hic! Hic! Can you feel your baby hiccup? That’s perfectly normal.
Your baby is now considered full-term. They could be born at any time!
The vernix caseosa, which acts as a protective layer on your baby’s skin, has now fallen off and floats in the amniotic fluid.
They’re waiting to be born. The uterus is feeling very small. Their limbs are bent close to the body and their chin is resting on their knees.
Your baby now has all the necessary reflexes to start developing in the outside world.
