Symptoms of spontaneous abortion Abdominal pain

Some women do not want the baby when they have an unexpected pregnancy, so they have an abortion. But you should know that in addition to artificial abortion, many mothers also experience natural miscarriage during pregnancy due to physical reasons. Unlike artificial abortion, pregnant mothers will experience some discomfort symptoms when they have a natural miscarriage. For example, the most common symptom is abdominal pain.

Abortion that occurs naturally (not caused by human intervention) is called spontaneous abortion. The incidence of spontaneous abortion is approximately 15% of all clinically confirmed pregnancies. Abortion occurring before 12 weeks of gestation is defined as early abortion, and abortion occurring between 12 weeks and less than 28 weeks of gestation is defined as late abortion. It is estimated that approximately 75% of all human pregnancies end in spontaneous abortion. Among them, most embryos stop developing soon after implantation, and only show symptoms of excessive menstruation or delayed menstruation, that is, early pregnancy miscarriage.

The main symptoms are vaginal bleeding and abdominal pain after the pregnancy is confirmed. Clinical types can be divided into:

1. Threatened abortion

Before 8 weeks of pregnancy, symptoms often include a small amount of vaginal bleeding, followed by paroxysmal lower abdominal pain or back pain. Gynecological examination showed that the cervix was not dilated, the fetal membranes were not ruptured, the products of conception had not been expelled, and the size of the uterus was consistent with the number of weeks of amenorrhea. After rest and treatment, some patients improved. If vaginal bleeding increases or lower abdominal pain worsens, miscarriage may become inevitable.

2. Miscarriage is inevitable

Means that miscarriage is inevitable. It develops from threatened abortion, at which time the amount of vaginal bleeding increases, the paroxysmal lower abdominal pain worsens, or vaginal discharge (rupture of membranes) occurs. Gynecological examination shows that the cervix is ​​dilated, and sometimes embryonic tissue or fetal sac can be seen blocking the cervix. The size of the uterus is consistent with the number of weeks of amenorrhea or slightly smaller. At this time, uterine contractions gradually intensify, and if they continue to progress, the pregnancy tissue may be partially or completely expelled, leading to incomplete or complete miscarriage.

3. Incomplete abortion

It means that some of the products of pregnancy have been expelled from the body, but some remain in the uterine cavity, which develops into inevitable miscarriage. Because some products of pregnancy remain in the uterine cavity, uterine contraction is affected, resulting in continuous uterine bleeding and even hemorrhagic shock due to excessive bleeding. Gynecological examination showed that the cervix was dilated and blood was constantly flowing out of the cervix. Sometimes placental tissue could be seen blocking the cervix or some products of pregnancy had been discharged into the vagina while some remained in the uterine cavity. The uterus is usually smaller than the number of weeks of menstruation.

4. Complete miscarriage

It means that all the products of pregnancy have been expelled, vaginal bleeding has gradually stopped, and abdominal pain has gradually disappeared. Gynecological examination showed that the cervix was closed and the uterus was close to normal size.
