How does my baby grow at 3 weeks?

At 3 weeks, your baby has transformed from a zygote into what’s known as a blastocyst, essentially a ball of cells. Some of these cells will become your baby, while others will develop into the placenta or amniotic sac.

The hormone hCG (human chorionic gonadotropin) will start being produced. This tells your body, specifically your ovaries, to increase oestrogen and progesterone production, which is what tells your womb to stop shedding its lining. This hormone is also what we detect when a pregnancy test is positive.

What are the pregnancy symptoms at 3 weeks?

Early on in pregnancy, food cravings may start kicking in. You might find yourself craving certain foods or finding foods that you previously liked very unappetizing. Common taste changes are with tea, coffee, alcohol (which you shouldn’t be drinking if you know you’re pregnant), fried food, and eggs. You might also notice a change in smell, particularly regarding perfume. Some mothers also report experiencing a metallic taste in their mouths.

The new hormones in your body can also leave you feeling tired and exhausted. This is because your body is starting to prepare itself to accommodate your baby.

What else do I need to know about being 3 weeks pregnant?
