Fourth week of pregnancy
What you need to know in the fourth week
The gestation period is usually two weeks after your last menstrual period, that is, around the time of your ovulation. (In pregnant women, ovaries are released from the ovaries every month, this is called ovulation.)
You may not notice any symptoms in the first 4 weeks of pregnancy.
The first thing a woman can understand when she is pregnant is that her period has stopped. There may also be other symptoms of pregnancy, such as breast tenderness. In some cases, there may be mild or occasional bleeding from the vagina during menstruation – this is due to the effects of menstrual hormones. There is usually no reason to panic. This can happen one or more times during pregnancy
However, if the amount of bleeding is high, you must seek medical attention without delay
Most women can be sure of pregnancy through pregnancy test.
You can calculate the probable date of delivery of your child by calculating from the last / first day of the last menstrual period, it is also known by the ultrasound scan. However, there may be some differences in the timing of these two methods.
What are the things to keep in mind?
- If you haven’t already started taking folic acid, start now without delay. Take 400 micrograms of folic acid tablet daily and continue taking it till the 12th week. Folic acid will protect your unborn baby from other neural tube-borne (brain / brain, spinal cord and nerve) problems, including spina bifida.
- Take 10 micrograms of vitamin-D tablets daily. Vitamin D will play a role in building baby’s bones and teeth.
- If you have diabetes or are overweight (if your BMI is over 30), you may need to increase your folic acid intake. However, no medicine should be taken in large doses without the advice of a doctor
How the fetus is growing
Early in pregnancy, the fetus begins to grow in the lining of the uterus, mainly in the 4th and 5th week of pregnancy. This embryo will transform into your full-grown baby in the future.
The cells on the outside of the fetus make contact with the mother’s blood supply. On the other hand, the cells inside the fetus are arranged in 2 to 3 layers in stages, and each layer later becomes a different part of the baby’s body:
- The inner layer is made up of different parts of the respiratory system (work: respiratory) and the digestive system (work: digestion), such as the lungs, stomach, intestines and bladder.
- The middle layer becomes the heart, blood vessels, muscles and bones.
- The outer layer is made up of the brain and nervous system, the lens of the eye, the enamel of the teeth, the skin and the nails.
During the early weeks of pregnancy, the fetus attaches itself to a small yolk sac that provides it with nutrients.
However, it is not possible for this small yolk sac to supply nutrients to the fetus throughout pregnancy. This requires the placenta or immortelle, also known as the placenta; It is fully prepared at the end of the next few weeks and is responsible for feeding the fetus.
The embryo is surrounded by fluid inside a sac called the amniotic sac. The placenta is formed from the outer layer of this sac.
During this time, the placenta cells begin to grow deeper into the uterine wall. In this way a strong blood supply system is developed, which ensures the supply of oxygen and nutrients to the fetus.
