Types of Miscarriage

As the pregnancy progresses, the type of miscarriages seen is different. The symptoms and the treatment modality also changes hand-in-hand.

The various types of miscarriages are:

 1. Chemical Pregnancy:

  • Seen in the initial stages of pregnancy after fertilization(sperm meets the egg ) within the first 5 weeks of pregnancy or a week before your next period
  • But due to chromosomal abnormalities in the fertilized egg, there is improper/failed implantation
  • The signs of chemical pregnancy is bleeding (slightly heavier than your period) that may occur a bit later
  •  50–75 percent of all miscarriages are chemical pregnancy as documented by the American College of Obstetricians and Gynecologists

2. Blighted Ovum

  • Synonymously know as anembryonic pregnancy
  • Occurs in the early stages of conception “after implantation”
  • The fertilized egg gets attached to the uterine wall (implantation), but the development of the embryo is hampered.
  •  Diagnosis of a blighted ovum is done on seeing an empty gestational sac and an absence of a heartbeat in ultrasound.
  •  Dilation and curettage (D&C) procedure is done for treatment

3. Missed Miscarriage:

  • The death of the fetus happens in the early phase of pregnancy phase and the tissue of pregnancy still remains within the mother’s body.
  • The symptoms of pregnancy continue
  • Cramping and vaginal discharge seen
  •  Dilation and curettage (D&C) procedure is done for treatment

4. Threatened Miscarriage:

  • Occurs in the first 20 weeks of pregnancy
  • Cramping with lower back pain which may/may not end in a miscarriage
  • It does not mean that your pregnancy will end in a miscarriage
  •   Cervix remains closed
  • When diagnosed with a closed cervix, the pregnancy is carefully monitored by the gynecologist

5. Inevitable Miscarriage:

  • The cervical canal dilation signifies that your body is in the process of miscarriage
  • Inevitable miscarriage is indicated by vaginal bleeding and abdominal pain that occurs during early pregnancy

6. Incomplete Abortion:

  • The cervix is widened and some portion of the fetal tissues is ejected
  •  Heavy vaginal bleeding and intense abdominal pain is seen
  • On an ultrasound, some tissue is still seen in the uterus

7. Complete Miscarriage:

  • The pregnancy tissue gets ejected in toto
  • Loss of pregnancy with severe abdominal pain and heavy vaginal bleeding
  • Decrease in  pain and bleeding after complete expulsion
  • On an ultrasound, no tissue is seen in the uterus
