The first trimester of pregnancy is a relatively sensitive period, and the first three months of pregnancy are the critical periods of fetal development and the most unstable period, because during this period, the embryonic differentiation period is easy to appear. If these conditions occur in the first trimester, do not be careless, which indicates that the fetus of the pregnant mother is unstable, which may be a sign of threatened miscarriage.
First, there is a feeling of falling pain in the lower abdomen, and there will also be paroxysmal abdominal pain
During the 12 to 14 weeks of pregnancy, there are many pregnant mothers who feel a tight feeling in their stomachs and also have a feeling of falling pain in the lower abdomen, which may be caused by irregular contractions, because the uterus will cause some pressure on the uterus when it contracts, which will cause some pain. In fact, this kind of pain mothers do not need to worry too much, usually more rest is good. If you do not only feel the pain in the lower abdomen, sometimes there is waist pain, distension, you have to pay attention to it, which may be a dangerous signal sent to you by the baby, indicating the danger of fetal threatened miscarriage, ectopic pregnancy and so on.
2. Vaginal bleeding
In the first trimester, many pregnant mothers have vaginal bleeding, but the number of occurrences is different. In general, vaginal bleeding is small, light in color, and does not last very long. What causes a small amount of vaginal bleeding? In fact, this is just a normal physiological reaction caused by the fetus implanting in the mother's body. So as long as the amount of bleeding is not much, mothers can rest assured.
However, if there is a lot of vaginal bleeding, and there will be mild lower abdominal pain, and the amount of bleeding continues to increase, it will be a big problem at this time, and it is likely to be a sign of "threatened miscarriage". Therefore, once vaginal bleeding is found in the first trimester, it is necessary to seek medical treatment in time to avoid delaying the timing of treatment and fetal protection and endangering the safety of the fetus.
Third, the serum H value or progesterone value is decreased
H, known as chorionic gonadotropin, is a glycoprotein hormone secreted by a cell in the placenta. Doctors diagnose early pregnancy by examining the level of H in the serum. Progesterone is a progesterone, its main role is to thicken the endometrium, blood vessels and glands proliferation, is conducive to embryo implantation, prevents uterine contraction, is conducive to the normal development of fertilized eggs in the uterus. If the pregnant mother's progesterone value is low, it indicates luteal insufficiency or premature decline of the corpus luteum, which can lead to difficulty implantation of the fertilized egg or threatened miscarriage in the first trimester.
Fourth, the early pregnancy reaction disappears
Generally speaking, one of the characteristics of the first trimester is that there will be an early pregnancy reaction, and many pregnant mothers say that they vomited at that time to doubt life, and felt that the organs in the stomach were going to spit out. However, if you don't vomit, it may be a bad thing, if the early pregnancy reaction disappears, but also accompanied by vaginal bleeding, then the mothers have to go to the hospital to check the HCG index to see if the fetus is stable. 【Popular Science】
