What tests should be done in early pregnancy? What is the purpose of these checks?

Last time I said I wasn’t worried about when the baby would come, and it was true. But when the baby entered my belly, I became very anxious. Throughout my pregnancy, I bought various books online and watched various popular science videos. Because of anxiety, I have to understand my baby's development at each gestational week. When will that organ grow, what can I do to make it develop better in my stomach, etc. I believe this is not my own worry, especially in the first trimester. New pregnant mothers are confused about early pregnancy check-ups. Because many articles on the Internet say that some examinations will affect the normal development of the baby in the first trimester, do we still do it? In fact, the first trimester check-up is only a part of the pregnancy check-up. It mainly checks the baby's living environment and allows the doctor to understand the baby's condition. Early examination usually includes the following items:

As you can see from the name, it is to use some equipment to examine the vagina and cervix of pregnant women to eliminate abnormal genital development of pregnant women and affect the smooth birth of the baby. Many mothers worry that these devices may adversely affect their babies. In fact, we really have to believe in science and it will not affect the baby. One of the reasons I recommend speculum exams is that these tests can help us determine the cause of bleeding in early pregnancy, whether it's the woman's vagina or cervix, or a problem with the baby. Routine examination of leucorrhea is very common among our old mothers, mainly to check whether there are infections such as trichomonas and mold. For pregnant women, it is very important to use leucorrhea to determine whether there is infection, because if there is infection, it can easily cause upward infection, affect embryonic development and lead to miscarriage.

Uterine examination, in fact, the professional term for gynecological examination is the third diagnosis. The main purpose is to understand whether the size of the uterus is consistent with the month of menopause and whether the embryo development is normal. When the size of the uterus does not coincide with the month of menopause, a B-ultrasound should be done to rule out uterine fibroids, abnormal uterine development, and abnormal embryonic development. It also includes whether the bilateral appendages are normal, whether the ovaries are enlarged, and whether the enlargement is functional or organic. I don’t know who said that ultrasound examination will affect the baby, such as deformities. Dr. Duan Tao, a famous obstetrician and gynecologist in China, said: In fact, early pregnancy ultrasound is also an important measure for us to implement patient safety: the "confirmation system" confirms that the mother-to-be and the child are fine! Confirm whether the embryo is a single or twin, extrauterine or intrauterine, whether the embryo is viable, etc. And after four months of pregnancy, B-ultrasound follow-up is also required according to obstetrics requirements.

If the mother suffers from heart, liver, kidney, thyroid and other diseases before pregnancy, she needs to consult obstetrics and gynecology and internal medicine to see whether she is suitable to continue the pregnancy. Especially if there have been multiple spontaneous miscarriages before, both couples should undergo a comprehensive examination. However, there is one test that is not appropriate during pregnancy - a CT scan. A CT scan uses X-rays to scan the human body, which are 100 times more powerful than ordinary X-rays. Even normal people can be affected by CT scans. If a pregnant woman undergoes CT examination in the early stages of pregnancy, it may cause fetal hydrocephalus, microcephaly or defects in the hematopoietic system. Therefore, I strongly recommend that you have a physical examination before pregnancy to confirm that there is no problem with the pregnancy and be responsible for yourself and your baby.
