50 days of pregnancy has been weak positive

During the first three months of pregnancy, pregnant women can hardly see any changes in their abdomen, and their appearance is no different from that of normal women. If it weren't for the obvious early pregnancy symptoms, it would be impossible to tell that you are pregnant. I think pregnant mothers really want to know how big the baby in their belly is in the early stages of pregnancy. What is the reason for weak yang at 50 days of pregnancy? How big is the baby at 50 days of pregnancy? Let’s find out together below.

What is the reason for weak yang after 50 days of pregnancy?

If the result of the early pregnancy test paper is weakly positive at 50 days of pregnancy, it generally indicates that the body's villus growth hormone level is low. If the villus growth hormone level is low during pregnancy, it is generally considered that the possibility of fetal growth arrest is relatively high, and it is better to have a follow-up visit for B-ultrasound examination.

How big is the baby at 50 days of pregnancy?

Around 50 days of pregnancy, the test tube embryo develops rapidly. The test tube embryo at this moment is about 1.2 centimeters long and looks like a cowpea. There are small gray-black spots on the face of the test tube embryo, which will be the baby's eyes in the future, and they are becoming clearer and clearer; the nostrils are wide open and the ears are deeply sunken. Changes in the area where the baby's hands and legs form are also becoming more obvious. The hands and feet of the test tube embryo now look like rowing oars. At this time, the hypothalamus, pituitary gland and muscle fibers begin to grow again.

How does the fetus grow and develop during early pregnancy?

1. One month into the pregnancy, the fetus cannot be called a fetus yet, it is called a test tube embryo, and the combination of sperm and egg is called a fetal bud or test tube embryo.

2. At 2 months of pregnancy, the fetus's test tube embryo already looks very much like a baby. When the two months are about to end, the hands and feet have already taken shape, and the eyes, ears, nose and mouth have also taken shape.

3. During the third month of pregnancy, the fetus can see nails, and has clear fingers and toes.

The whole process of growth and development of fetal taste buds (taste):

1. How many senses of taste do people have?

There are many particles on the human tongue, but these particles are not taste sensations, they are just fungiform papillae. Each mushroom-shaped papilla contains 50 to 100 taste buds. The mouth can sense five flavors: bitter, spicy, sour, sweet, and salty. There are only a few ways to feel sweet, sour, salty, and fresh, but there are at least 25 ways to feel bitter. The benefit of being so sensitive to bitter tastes is that it prevents us from being poisoned.

When a baby is born, its tongue is already covered with 10,000 taste buds. As they age, women gradually lose them when they are 40 to 50 years old, while men lose them later, around 50 to 60 years old. The old taste is not easily replaced by the new one, it just fades away completely, which is why adults have a significantly heavier taste than children.

2. The wonders of fetal taste

Can distinguish sweetness and bitterness in the 7th month of pregnancy

During the third month of pregnancy, the fetus's sense of taste gradually develops and is basically complete around the seventh month of pregnancy. Therefore, the fetus has the ability to sense taste around July and can distinguish sweet and bitter tastes.

Taste the amniotic fluid of pregnant women

In the first half of pregnancy, the fetus drinks about 1 liter of amniotic fluid every day on average. In addition to water, the components of amniotic fluid also contain fetal urine, salt, sugar, oleic acid, cholesterol, etc. Moreover, as the expectant mother's diet changes, the taste of the amniotic fluid will also change. The fetus can taste, and there is a sense of taste on its tongue that can distinguish tastes, so when they drink the amniotic fluid of the pregnant woman, they can taste the taste of the amniotic fluid of the pregnant woman.

Born with a love for desserts

The fetus's sense of taste has been fully developed at birth. After birth, it can immediately distinguish the difference between milk and other tastes. It is born with a preference for sweet foods and a dislike for salty tastes. This may be a code written in the genes, because our ancient ancestors could not immediately distinguish whether food was toxic or not, and could only rely on taste, and it happened that most sweet foods were non-toxic. Fetuses and newborns are not easily disgusted by sweet tastes. They will accept all tastes given by their mothers and take them all. In other words, during pregnancy and breastfeeding, the fetus will think that all the food the mother eats is safe, and will gradually accept and get used to these tastes.
