Week 4 symptoms

Expect noticeable pregnancy symptoms during the 4th week. The week 4 symptoms are as follows:

Over fatigue

Over fatigue is the body’s natural response in preparation for pregnancy. During the first few weeks of pregnancy, the female body is working on the inside to adjust for the motherhood stage.

The excessive progesterone that is produced can cause the basal body temperature to surge. This then will decrease energy levels which makes her feel over fatigue.

Pregnancy week by week

Other than that, the heart pumps faster during pregnancy too since it has to deliver extra oxygen to the uterus.

Frequent urination

Expect frequent trips to the bathroom once a woman becomes pregnant. Frequent urination is caused by the following sources:

  • The uterus swells as the baby develops. The swelling uterus causes some pressure to the bladder which causes the woman to urinate frequently
  • Excessive blood flow through the kidney also triggers the system to produce more urine

Food cravings and aversion

Food cravings is said to be the body’s way of protecting the developing baby. A woman starts to crave for some certain food in as early as 2 weeks after conception.

Developing a distaste to some certain kind of food (food aversion) is the body’s defensive mechanism to steer away free radicals and nitrates which can harm the fetus.

Breakthrough bleeding

Breakthrough bleeding occurs when pregnancy hormones cover up the normal menstrual cycle however, the cycle continues for a while. This type of bleeding may happen more than once during the 4th week.

Morning sickness

Did you know that about 1% out of 25 women experience sickness in the morning? The term for this symptom does not accurately describe that she will just feel sick during the morning. This symptom can strike in anytime of the day.

In addition to that, about 1% out of 3 women do not vomit when suffering from morning sickness. Oftentimes, morning sickness is accompanied with queasiness the moment she wake up. Unfortunately, some women endure this symptom for months.

Vomiting

Did you know that about 1% out of 100 women experience hyperemesis gravidarum in pregnancy? Since the process of digestion is slow during pregnancy, a woman purges what she have eaten through her mouth instead (vomiting).

Hyperemesis gravidarum (severe vomiting) is a rare pregnancy condition where women struggle to anything down their stomach. It is also considered as the most severe form of morning sickness.

Below are the following indications of suffering from HG:

  • Sensitive sense of smell
  • Excessive saliva
  • Vomiting is prolonged and severe
  • Vomiting in between meals
  • About 5% pregnancy weight loss
  • Suffering from dehydration

A pregnant woman is at higher risks of suffering from HG if:

  • Expecting her first child
  • Carrying a baby girl
  • Carrying twins or triplets
  • Prone to migraine
  • Prone to motion sickness
  • Teenage pregnancy
  • Overweight in the start of pregnancy
  • Hereditary HG

If HG started after the 12th week of pregnancy which is accompanied with fever and pain, there may be another causes:

  • Gastric upset
  • Urinary tract infection (UTI)
  • Thyroid disorder
  • Diabetes

HG usually occurs between 4-7 weeks. This condition relieves about 15 weeks of her pregnancy. In some cases, HG ends around the 20th week of pregnancy. Unfortunately, some women experience HG up until the end of their pregnancy.

Sore breasts

The breasts begins to become sore in as early as week 2 and/or after conception. This is because the body is producing plenty of oestrogen and progesterone. Thus, these hormones trigger the growth of the glands inside the breast.

The fluxes of homrone production also causes the breasts to conserve more fluids and feel heavy, tender, and sore.

Bloating

Bloating is caused by the production of progesterone (pregnancy hormone).

Cramping and bleeding

Cramping and bleeding is caused by the baby’s implantation to the uterine wall.

Headache

Headache during pregnancy is mainly caused by the increased levels of progesterone. It can also be a cause of the following sources:

  • Dehydration
  • Anemia
  • Hormonal fluctuation

However, the occurrence of migraine decreases as the pregnancy progresses.

Mood swings

Mood swings is caused by the fluctuation of pregnancy hormones. This symptom is most drastic during the first 12 weeks of pregnancy.

The baby in week 4

The baby which is currently a blastocyst (ball of cells) is now an embryo in week 4. The unborn baby is currently about the size of a poppy seed at this point. Below are the step-by-step procedure of how the baby is growing this week:

  1. Embryo divides into three layers which later form into placenta, organs, and tissues.
  2. The neural tube begins to form in the top layer. This is where the brain, backbone, and spinal cord begins develop.
  3. The inner layer (endoderm) which will form the baby’s digestive system, liver, lungs, and urinary tract.
  4. Next is the middle layer (mesoderm) which will form the heart, bones, muscles, sex organs of the baby.
  5. The last layer, the outer layer (ectoderm) which will form the baby’s nervous system, skin, hair, and eyes.
  6. The amniotic sac (also called the bag of waters) forms into a protective cushioning for the baby. Then the yolk sac follows and begin to produce red blood cells (RBC) and nutrients for the developing baby. Additionally, the yolk sac will later be incorporated to the baby’s developing digestive tract.
  7. Placenta cells begin to burrow into the uterine lining, which will develop into a chorionic villi (microscopic fingers of tissues).
  8. Once the placenta is fully functional and developed, it will replace the yolk sac from supplying nutrients and oxygen to the baby. The placenta also takes away the baby’s fecal matters. Other than that, the umbilical cord distributes the nutrients and oxygen to the baby.
  9. Then the baby continues to grow and develop for nine months.
