1 Month Pregnancy: Hormone Change and Morning Sickness

When you are 1 month pregnant, you don't look like a pregnant person. But it may have felt certain symptoms, including late menstruation, nausea, and vomiting, or often referred to as morning sickness.

Fertilization usually occurs about two weeks after the first day of the last menstruation, around the time after the body produces eggs. Until when it reaches 1 month of pregnancy, the fetus is still a collection of cells called embryos, which continue to divide and develop into small babies in the following months.

How is 1 month fetal growth?

When pregnant 1 month or 4 weeks, the baby still resembles a small point about 0.8 inches (0.2 cm) long. The cells in the embryo cluster to then develop into body parts.

1 Month Pregnant




4 weeks pregnant

The embryo begins to develop in the womb. The outermost cells begin to form tissue to the mother's blood supply. While the inner cells are formed into two, then three layers, and then develop into the baby's body. The layers are:

  • Endoderm: the innermost layer that forms into the respiratory and digestive systems, such as the lungs, intestines, stomach and bladder.
  • Mesoderm: the middle layer that develops into muscles, bones, heart and blood vessels.
  • Ectoderm: the outer layer which then becomes the nervous system, brain, tooth enamel, nails, eyepiece, and skin.

This week, the embryo attaches to the yolk sac that supplies nutrients to the fetus. In the next few weeks, this function will then be replaced by the placenta. The placental cells that develop in the uterine wall provide blood flow which ensures that the fetus gets enough nutrients and oxygen.

5 weeks pregnant

  • During this time, women are generally just beginning to realize that they are pregnant because of being late for the month.
  • The baby's nervous system and main organs begin to develop.
  • A hollow tube or neural tube is formed as the development of the ectoderm layer which then becomes the spinal cord and baby's brain. Abnormalities in the end of the neural tube can lead to spina bifida or neural tube defects. Meanwhile, abnormalities in the part of the neural tube head result in anencephaly or a condition when the cranium is not properly formed.
  • The heart and vessels have begun to form. At this time, blood circulation has begun to work. A blood vessel will form, which will then develop into a cord, to connect the baby's blood circulation with the mother.

6 weeks pregnant

  • The embryo starts to be crescent shaped and has a tail so that it looks like a tadpole with thin translucent skin.
  • A protrusion at the end of the neural tube will develop into the head and brain.
  • When an ultrasound is performed, the heart can begin to look pulsing.
  • Feet and arms will begin to appear.
  • There are small basins on both sides of the head that will develop into ears. There are also areas with thickened surfaces, which will develop into eyes.
  • His heart has beaten 150 beats per minute.

7 weeks pregnant

  • The embryo has grown to 10 mm.
  • The brain has developed so rapidly that it makes the head grow faster and larger than it does
  • The embryo appears to have a large forehead with an expanding eye and inner ear.
  • Cartilage begins to form and begins to develop into the bones of the arms and legs.
  • Nerve cells begin to multiply and develop into the nervous system.

Changes that Occur During 1 Month Pregnancy

At 3 weeks' gestation, many people don't realize that they are pregnant because they don't feel any symptoms. But some women may feel an increase in vaginal fluid volume, a little cramping, back pain and headaches.

When you are 7 weeks pregnant, your uterus has grown to the size of a lemon. You may feel weak, get tired easily, your breasts feel enlarged and painful, and you want to urinate more often.

About 90% of pregnant women feel nausea and vomiting early in pregnancy, known as morning sickness. These symptoms are a sign that pregnancy hormones in your body are enough to support pregnancy. Women who experience nausea at the beginning of pregnancy have a lower risk of miscarriage than those who do not experience nausea. Although it does not mean that women who are not nauseous, they cannot get a healthy pregnancy.

What do you need to check?

You may need to try a pregnancy examination with the testpack more than once. Some women need to wait up to 2-3 weeks after being late for the month so that pregnancy hormone levels are high enough to be detected. After a positive pregnancy, you and your partner should consult your obstetrician immediately.

Some women can feel symptoms of morning sickness that are more severe than others, until they are unable to carry out normal activities. If not handled properly, this condition can cause depression, even interfere with the health of pregnant women and the fetus.

Early nausea in pregnancy can also be very severe, otherwise known as hyperemesis gravidarum (HG). This situation is characterized by a high frequency of vomiting, being unable to eat and drink and losing weight. HG can also affect baby's health. Therefore, if nausea is felt to be very disturbing, immediately check with the doctor to get proper treatment.

Things to Look For During 1 Month Pregnancy

The following are things you can do and need to avoid when you are 1 month pregnant:

  • If morning sickness is not too disturbing, continuing to exercise can make the body stay fit. Choose the right exercise during pregnancy.
  • Remember that your fetus will take part in and get the effects of everything you consume. Avoid cigarettes, caffeine, illegal drugs, liquor, and certain foods such as raw foods that can be harmful to the fetus.
  • Also consult all medicines that are being or will be taken, both over-the-counter and prescription drugs.
  • Lifestyle changes, such as avoiding cigarettes and liquor, also apply to your partner. Cigarette smoke inhaled by pregnant women can adversely affect the fetus.
  • Take folic acid supplements for pregnant women, which also contain iron.
  • Changes in the womb and physical changes in pregnant women can make the body tired. Make sure you get enough rest every day.

Even though there have not been many changes that appear on your body during 1 month of pregnancy, there have been many changes that occur in the womb. Entering the 2 month gestation later, the volume of blood in the body will increase 40-50 percent. Meanwhile, the limbs will appear more in the embryo.
