How big is the fetus at one month of pregnancy? Things to know for prospective parents

When you are one month pregnant, the fetus is just a small embryo, only 0.2mm in size and even lighter in weight, 1.505μg. At this time, you cannot see it very clearly through B-ultrasound. If you use a test strip, you will find two bars, which means you are successfully pregnant.

1. Fetal development

This month's fetus is still a fertilized egg, about 0.2mm long and weighing 1.505μg. It is called a "germ" or "embryo". It looks very, very small now! Through B-ultrasound, we can see that its shape is like a small pine nut.

At one week of pregnancy, there is no fetus yet. The sperm and egg are in your body and your partner's body respectively. The fertilized egg is formed at 3 weeks of pregnancy and implants at 4 weeks of pregnancy. At this time, the amniotic cavity is formed, but its size is very small. B-ultrasound cannot clearly show signs of pregnancy.

The fetus is now very inconspicuous, about 0.2cm long, very small and soft. The fetus that has just implanted in the uterus does not yet look like a "human" in appearance. Its head is the same size as its body and looks like a fish with four gills and a long tail.

By the end of this month, the prototypes of various organs begin to appear, and the placenta and umbilical cord also begin to develop. Although the fetus' heart is no bigger than a poppy seed, it has already begun to beat.

2. Must-read for prospective parents

1. Confirm pregnancy: If you find that your period, which used to be very regular, is 10 days late, your breasts are inexplicably enlarged, the color of your areola darkens, you feel mentally fatigued, and other symptoms, you should suspect that you are pregnant. You can conduct a preliminary test with a pregnancy test strip. If you get a positive result, go to the hospital for a detailed examination to rule out common pathological pregnancies such as ectopic pregnancy and hydatidiform mole.

2. Calculate your due date: You can calculate your due date based on your last menstrual period date. The method is: month = last menstrual month + 9 (or -3); date = last menstrual date + 7.

3. If you are pregnant unexpectedly and plan to give birth to the child, you need to inform your unit leaders and colleagues as soon as possible so that they can arrange your work. You may feel more easily tired at work. You can explain the situation to your leader and take a short rest in the lounge to replenish your energy.

4. Medication for pregnant women: It is easy to get sick in the early stages of pregnancy, and you may easily get symptoms such as colds and coughs. At this time, remember not to use medication indiscriminately. For common colds, try to drink more water and focus on diet therapy. If the cold symptoms are severe, you should go to the doctor and follow the doctor's advice.

5. Reasonable diet: Many expectant mothers start taking a lot of supplements as soon as they are diagnosed with pregnancy. In fact, at this stage, the baby is still young, and if you eat too much, you basically grow your own flesh, but the baby does not absorb it. The correct dietary principle is to combine meat and vegetables, and avoid foods that are prohibited for pregnant women.
