How to calculate the pregnancy period

When women learn that they are pregnant, the burden on their shoulders is very heavy. They have to overcome one challenge after another, avoid doing things that are not conducive to their babies during pregnancy, adjust their living habits, ensure sufficient golden sleep time, and calculate their pregnancy period. How should the pregnancy period be calculated?

Week 1

Now that you have started preparing to have a lovely baby, you should prepare the internal environment of your body and the external environment of your life. The internal environment refers to maintaining a healthy body and mentality. You should quit smoking and drinking at this time, because excessive smoking and drinking can cause sperm and egg abnormalities. You definitely don't want your baby's life to start in an abnormal state. During a planned pregnancy, avoid contact with toxic substances such as anesthetics, pesticides, murderers, lead, mercury, cadmium, etc., and avoid exposure to radioactive substances such as X-rays. At this time, you should keep your body relaxed and comfortable, and avoid getting pregnant during high-intensity exercise or when you are overly tired. The external environment refers to the living room which should be kept fresh and clean, and the small family should be decorated as romantic and warm as possible to create a harmonious and light atmosphere.

Now you can calculate your ovulation cycle, or menstrual cycle, yourself. The main method is the basal body temperature method, that is, after waking up every morning, the body temperature is measured with a thermometer without any exercise. After doing this for a month, you can create a curved basal body temperature chart. Generally, the body temperature will rise by 0.3 to 0.5 degrees during ovulation. According to the basal body temperature chart, you can be prepared to welcome a new life during the ovulation period.

Week 2

Entering the late second week, you will find that you have entered the ovulation period based on your basal body temperature, and now you should be ready. The basal body temperature method is determined based on the menstrual cycle, which refers to regular, cyclical uterine bleeding. It is related to the periodic maturation of ovarian follicles, ovulation and corpus luteum formation in the ovaries. The follicles mature around the 5th to 13th day of the menstrual cycle, at which time the endometrium proliferates. After ovulation, around the 14th to 23rd day of the menstrual cycle is the corpus luteum maturation stage, when the endometrium continues to thicken. If there is no fertilization, the endometrium will fall off and become menstruation. Normal menstruation lasts 2 to 7 days, with the heaviest bleeding on the 2nd to 3rd day, approximately 20 to 60 ml. Therefore, the 13th to 20th day is your best pregnancy period. You can work with your husband to adjust your physical health and complete your mission at the best time.

A healthy baby comes from healthy parents. As a mother, you should try to supplement folic acid before 3 months of pregnancy, because folic acid is one of the three major hematopoietic raw materials in the human body and can promote the production of red blood cells. If folic acid is lacking in early pregnancy, it will affect the normal development of the fetal nervous system and lead to neural tube defects such as spina bifida or anencephaly. Therefore, the US Centers for Disease Control and Prevention has recommended that women of childbearing age should supplement 0.4 mg of folic acid every day, and pregnant women should take about 1 mg per day.

Week 3

The egg is the largest cell in the human body, with a diameter of up to 200 microns and a lifespan of only 12 to 36 hours in the fallopian tube. The sperm is about 500 microns long and is divided into a head, neck and tail. It moves like a tadpole relying on its tail. Sperm can survive for 3 to 5 days in a good cervical mucus environment, but conception usually only occurs within 24 hours after sexual intercourse. At this time, the sperm and egg have combined to form a fertilized egg, which is 0.2 mm in size and weighs 1.505 micrograms.

The fertilized egg reaches the uterine cavity after 3 to 4 days of movement. During this process, it divides from a single cell into multiple cells and becomes a solid cell mass with a constant total volume, called a morula.

Week 4

It's already the 4th week, have you not noticed any changes in your body?

During this period, the embryo has "implanted" in the uterus, or "implanted." It takes about 4 to 5 days to complete implantation, and three conditions must be met. Namely, the zona pellucida must disappear about 7 days after fertilization, allowing the blastocyst to be released and in direct contact with the endometrium; the endometrium proliferates and secretes vigorously, the interstitial edema, and the blood vessels dilate and become congested; the cells surrounding the cyst differentiate into two layers of trophoblasts and syncytial cells, among which the syncytial cells can secrete protease that dissolves the endometrium, allowing the blastocyst to implant.

After implantation, the embryo grows slowly. At this time, the development of the brain has begun. The fertilized egg continues to divide, one part forms the brain and the other part forms nervous tissue. At this time, special attention should be paid to strengthening nutrition. Rich nutrition will provide a good growth environment for brain cells and nervous system.

You may experience mild discomfort and sometimes fatigue during this period. Don't worry, you will soon enter a colorful pregnancy life

The above is a detailed explanation of how to calculate the pregnancy period. Everyone should have a good understanding of it, so during the pregnancy process, you can learn to calculate your own pregnancy period to find out what state your baby has entered.
