The most significant symptomatic reactions to miscarriage are vaginal bleeding and abdominal pain. There are several types of miscarriages: aura miscarriage, inevitable miscarriage, incomplete miscarriage, complete miscarriage, premature miscarriage, habitual miscarriage, and infected miscarriage. In the case of preterm miscarriage, there may be only a small amount of vaginal bleeding with or without lower abdominal cramps and lower back pain, at which time we recommend the patient to rest in bed. An inevitable miscarriage will present with increased vaginal bleeding, increased minor pain, and even the flow of amniotic fluid. Incomplete miscarriage means that the fetus has been expelled, but there is a placenta partially or completely left in the cervix. A complete miscarriage is when the fetus and placenta are completely expelled, when the bleeding decreases or stops and the abdominal pain disappears. Late miscarriage means that the embryo has been dead in the uterus for more than 2 months and has not been expelled spontaneously. The patient’s early pregnancy reaction disappears and there may be recurrent vaginal bleeding, which may be more or less frequent. Habitual miscarriage refers to the occurrence of more than 3 times in a row, which we call habitual miscarriage. The last type of miscarriage is infectious miscarriage, which is caused by prolonged bleeding, residual embryonic tissues in the uterus, or aseptic operation during surgery, etc. In this case, the patient will have symptoms such as increased body temperature, increased pulse rate, lower abdominal pain and foul-smelling vaginal discharge. By knowing the different types of abortion, patients can be unnecessarily scared when problems arise.
