First trimester weeks

Congrats! During the first trimester, you’re getting used to the idea of being pregnant.

Second trimester weeks

As you enter this second trimester, your body will settle down to pregnancy.

Third trimester weeks

You've reached the third and final trimester and will be heavily pregnant by now.

Week 6 of Pregnancy

This week you may notice the first symptoms of pregnancy-if not, don't worry.
Not all women start to feel pregnant this early on. Some experience a twinge of nausea or breast tenderness, while others notice no changes. Of course, it's natural to long for "proof" that your pregnancy is progressing, even if that happens to be morning sickness. But a lack of symptoms doesn't mean something is wrong, it's all really happening and your baby is going through some critical stages of development.

Your baby today

This image shows just how curled up the embryo is at this stage. The head end of the embryo is on the right. The embryo now has 22 pairs of somites (building blocks of the musculoskeletal system) running along the back.

This is a crucial time for your developing baby as the neural tube, which will become the brain and spinal cord, is forming.

This week your baby begins to grow rapidly and will become much more recognizable as a baby over the next five weeks. There are three types of cell, each committed to a separate function. The first will form the skin and nervous system; the second forms blood vessels, muscles, and bones; the third forms the entire digestive system.

At this stage, it is the cells responsible for the spine and nervous system that are at work. Changing shape from a flat disk, the embryo starts to curl up. The edges of the groove that has already partially formed along the back gradually start to meet, closing and fusing to form a tube, which will become the brain and spinal cord. The last parts of the tube to close are at the very top of the head and then the base of the spine, two days later.

Being careful to get an adequate intake of folic acid in early pregnancy is essential to ensure the neural tube closes completely, with no gaps.

Keeping quiet

Your first reaction to finding out that your partner is pregnant might be to tell the world. After all, you may be excited or nervous and may want to confide in people who you can trust. Think twice before telling lots of people and don't do so without talking to your partner. Of course your partner may find it hard to hide some aspects of pregnancy, such as morning sickness.

Most importantly, make sure that you are both in agreement that it is the right time to tell others.

Not telling many people, if anyone, in the first few weeks will give you both time to come to terms with the news.

Whether to tell

You're excited to be pregnant, but should you tell people yet?

  • Most parents-to-be wait to share their exciting news until after week 12 when the risk of miscarriage falls. You, may, however, decide you want to confide in family and close friends. If they are people whom you would tell if you miscarried, then there is no harm in sharing your news.
  • Most women don't tell their employers yet, unless severe morning sickness interferes with their ability to keep up with work responsibilities. Most wait until after the first trimester or when they start to show. If you want time off for prenatal appointments before this, you'll need to explain why.
  • Similarly, if your job involves anything that could be a health and safety risk (for example, heavy lifting or working with chemicals), you should inform your employer early so your role can be adapted. Itâs also sensible to tell your boss the good news before office gossip about your expanding girth snowballs.
