Baby Development

How is my baby growing?

Although you may not feel pregnant but there is a baby is growing and developing inside you. Fertilized eggs will undergo a process of cell division. About 30 hours after fertilization, the egg will divide into two cells, then four cells, then eight, and continues to divide until moving from the fallopian tube to the uterus. As to the uterus, this group of cells looks like a tiny ball and is called an embryo.

The embryo will become hollow and filled with fluid – known as a blastocyst. Near the end of the week, the blastocyst will attach itself to the uterine lining. This process is called implantation. Implant in the uterus creates an essential connection: endometrium will provide nutrients and waste removal for the developing embryo. Over time, the implant will develop into the placenta, which will help nourish your baby for the next 9 months.

Body & Life Changes

How is my body changing?

Your body is going through multiple changes to support your fertilized egg. At this time you may not know you’re pregnant yet. You may notice a little spotting by the end of this week. This is called “implantation spotting.” This means the fertilized egg has attached to your uterine lining. Not all women will experience this spotting and some women may mistake the spotting for their period.

What should I be concerned about?

Morning sickness, like craving pickles and ice cream, is one of the obvious symptoms of pregnancy but not necessarily occur in all cases. Research shows that nearly three quarters of all women with nausea and vomiting related to morning sickness and a quarter of the rest will not experience this pregnancy symptom. If you are among those who never felt nauseated, or only get occasional or mild nausea, you are a very lucky expectant mother.

Three-quarters of pregnant women will suffer morning sickness all day. However, please rest assured, even if you have difficulty eating and lose weight in the first three months of pregnancy, this will not hurt your baby, as long as you can regain the weight plus more later. Regaining weight will be quite easy because of nausea and vomiting will disappear by the mid-week 12 to the week 14 of pregnancy.

Doctor Visits

What should I tell my doctor?

Speak to your doctor immediately if you suspect that you are getting pregnant. Your doctor may tell you to use a pregnancy test. You may not need to see the doctor until the 8 weeks of pregnancy.

What tests should I know about?

The best way to confirm your pregnancy is to use a home pregnancy test. You can buy this at your local pharmacy. The home pregnancy test can test as early as the first day you miss your period. You can buy multiple tests to confirm your results. The tests measure a specific hormone that is found in your urine. This hormone is called Human Chorionic Gonadotropin (HCG). It is released by the placenta. Depending on the type of pregnancy test. A positive result will show you either a plus sign or 2 pink lines.

Health & Safety

What should I know about being healthy and safe while pregnant?

Nurturing a baby inside of you for 9 months is not easy. You may worry about how this will change your social life, how you will manage work or if what you are eating is safe for the baby. You should know that your baby’s development does not only depend on what you eat but your emotions can affect your baby too.

When you worry or feel anxious, your body produce a stress hormone called corisol. This hormone can cause your heart to increase and trigger an inflammatory response in your body. Many studies have shown a link between inflammation and poorer pregnancy health, leading to developmental problems in babies. In addition, women with stress in the first trimester of pregnancy have a higher risk for a miscarriage.

For your safety as well as your growing embryo, here are some tips to manage your stress during pregnancy:

  • Talk to someone. You may not want to burder your partner or friend with your problems but it does not help to keep it to yourself. Try talking to someone. You will see that you will feel better afterwards.
  • Relax. Meditation and relaxation techniques can help. You can even make yourself a warm cup of tea or read your favortite book.
