Generally speaking, women are always paying attention to their own changes after they become pregnant, because every discomfort in the body may be related to the well-being of the fetus, and not every pregnant woman experiences the same thing, so they have to pay attention to themselves. However, as a parent, there are many issues related to the baby's development that need to be addressed, such as how big is the baby after one month of pregnancy?

Your gestational month is four weeks from the first day of your due date. At this time, the fetus in the belly is about millimeters long, like a small seahorse (the fetus before 7 weeks is called the fetal bud, and the spine and neural groove have already formed at this stage). The vast majority of pregnant women do not have active symptoms, but a small number of them may experience cold-like symptoms: fatigue, fever, chills, etc. At this time, there is no visible change in the size and shape of the uterus and breasts. They are similar to those before pregnancy, with the uterus being about the size of an egg.

Baby development indicators in the first week of pregnancy, changes in the pregnant mother's body: the uterus is as big as an egg, which is no different from before pregnancy. Some people will feel nothing, while others will experience symptoms such as fever, breast swelling, etc. Entering the middle and late second week, you can find that you have entered the ovulation period based on your ovulation temperature, and now you should be fully prepared. The ovulation temperature method is determined based on the menstrual cycle. The egg is approximately perfected on the 5th to 13th day of the menstrual cycle, and the 13th to 20th day is the best pregnancy period. Pregnancy usually only occurs within 24 hours after sexual intercourse. At this time, the sperm and egg have already merged to form a sperm-egg combination, which is 0.1 cm in size and very light in weight. At this stage, the test tube embryo has already implanted in the uterus, or is called "embedded". It takes about 4-5 days for the embryo to implant. After implantation, the test tube embryo grows slowly. At this time, the growth and development of the human brain has already begun. The sperm and egg combine and continue to disintegrate, one part produces the human brain, and the other part produces nerve tissue.

After the fusion of sperm and egg to form sperm-egg union, the embryo implants and the sperm-egg union gradually disintegrates into a multicellular fetal sac. After more than thirty days of pregnancy, each primitive cell begins to divide and gradually forms a fetal bud and fetal heartbeat, which further develops into a fetal heartbeat. This is the whole process of a fetus being born. Generally, the period from the third week of pregnancy to the first month of pregnancy is called the embryonic bud and fetal heart stage. At this time, blood data signals of heart beats can be seen during B-ultrasound or ultrasound examination, and further development will lead to the formation of a fetus. For normal intrauterine pregnancy, B-ultrasound examination can usually show the fetal heartbeat and fetal heartbeat in the uterine cavity at 6-7 weeks of pregnancy. If there is still no embryonic bud, fetal heartbeat or fetal heartbeat after seven weeks of pregnancy, the expectant mother should consider the possibility of embryo termination and go to the hospital immediately to check the condition of the fetus.
