Signs of miscarriage during the second trimester

Pregnant women can feel the movement of the fetus in their belly at a certain period of time. This period is called the second trimester. The second trimester generally refers to the time between weeks 14 and 27 of a woman's pregnancy. The placenta has been formed during this period and the fetus is relatively safe. However, there is also the possibility of miscarriage at this time. Therefore, mothers in the second trimester must pay attention to physical symptoms to prevent miscarriage. So, what are the signs of miscarriage during the second trimester?

1. Reduced fetal movement Fetal movement is one of the most objective signs of fetal life and is a signal sent by the fetus to the mother. Therefore, pregnant women should keep track of fetal movements to understand the safety of the fetus and detect problems in time. Normally, between 16 and 20 weeks of pregnancy, the fetus begins to have noticeable fetal movements that can be felt by the mother. As the gestational age increases, fetal movements also increase. After 30 weeks of pregnancy, a normal fetus will move at least 3 times per hour, and the number of fetal movements within 12 hours will be about 30-40 times or more. However, it is normal for a fetus to have reduced fetal movement as it approaches full term, which may be related to the fetus's sleep condition. Fetal movement can be affected by many factors. The month of pregnancy, the amount of amniotic fluid, the posture of the pregnant woman, etc. can all cause fetal movement to change, but these changes are within the normal range.

2. Unexplained abdominal pain During pregnancy, pregnant women may feel mild abdominal pain at certain stages, which is generally normal. But if the abdominal pain is sudden and crampy, it needs to be taken seriously. In early pregnancy, severe lower abdominal pain accompanied by vaginal bleeding may be a warning sign of ectopic pregnancy or threatened miscarriage.

3. Amniotic fluid amount: Amniotic fluid is one of the elements to maintain fetal survival. Too much or too little amniotic fluid may be a warning sign of fetal disease. Pregnant women need to be alert if abnormal amniotic fluid volume is found during examination. The functions of amniotic fluid include not only expanding the uterine wall and providing the free space needed for the fetus' growth and development, but also cushioning the uterus when it is impacted by external forces, maintaining a stable temperature, and assisting in dilating the cervix by transmitting pressure through the water bag during labor pains. Therefore, amniotic fluid is regarded as the "water of life" for the fetus. Amniotic fluid is mainly formed by the placental tissue osmotic fluid in the pregnant woman's uterus and the fetal urine.
