Early Pregnancy Loss (Miscarriage)

Obstetrics, Abnormal Pregnancies, Early Pregnancy Loss, Menopause Center of Los AngelesEarly pregnancy loss, also known as a miscarriage or spontaneous abortion, occurs in the first trimester of pregnancy. It’s a fairly common occurrence, affecting an estimated 10% of known pregnancies.

The fact is, early pregnancy loss occurs in more than 10% of pregnancies; however, the women who face them don’t always realize they were pregnant at the time.  Sometimes, an early pregnancy loss just looks like a period that came a little later than expected.

Causes of Early Pregnancy Loss

Each case of early pregnancy loss is different, and we may never know the exact cause. Research shows that about half of early miscarriages result from the abnormal chromosomes in the embryo. We also know that your risk of early pregnancy loss increases as you get older.

  • Having sex
  • Working
  • Exercising
  • Using birth control pills before pregnancy
  • Falling
  • Getting hit in the tummy
  • Being startled or “spooked”

Many researchers have looked into the question of whether substances like alcohol, caffeine, and tobacco can cause miscarriage. The results are mixed.

  • Some studies suggest that smoking increases the risk, while others found no impact. Doctors highly recommend that you completely abstain from smoking during pregnancy.
  • Drinking alcohol in the first trimester may slightly increase your chances of losing the pregnancy, but it’s hard to say for sure. To be absolutely certain that alcohol has no impact on your pregnancy, doctors highly recommend abstinence.
  • Thankfully, caffeine does not seem to have an effect on your chances of miscarriage, as long as you have no more than 200mg per day. For reference, one cup of coffee contains about 100mg.

Symptoms of Early Pregnancy Loss

The most common symptoms of an early pregnancy loss are bleeding and cramping, but these are not sure signs. Many women experience these in their first trimester, and their pregnancies continue normally.

Diagnosis of Early Pregnancy Loss

If you are bleeding and cramping, please contact us. Bleeding and cramping may be signs of other serious complications, such as an ectopic pregnancy. We can perform a physical exam and an ultrasound to check on the development of the fetus. We may order blood tests to further evaluate the cause of these symptoms.  It’s important that we check on you and take every precaution to ensure your health and safety.

What Will Happen if the Pregnancy Is Lost?

If you have miscarried, we need to make sure all the pregnancy tissues are removed from your uterus. There are both surgical and non-surgical options available.


If there’s no risk of infection, it may be possible to allow the tissue to pass naturally, which usually takes 1-2 weeks. If necessary, your doctor can prescribe medication to help it pass more easily.

You should expect bleeding that is longer and heavier than your normal period. You may also pass tissue that resembles blood clots. Symptoms can include nausea, diarrhea, and/or painful cramps, for which we can prescribe you medication. Afterward, you should have an ultrasound to make sure all of the tissue has passed.


If your bleeding is heavy, or if you show signs of an infection, we will recommend surgical removal of the tissue. There are two common procedures:

Vacuum aspiration

This procedure can be performed in our office. It involves inserting a thin tube into the uterus, and using gentle suction to clear out the tissue. A local anesthetic can be used to make you more comfortable during the procedure.

Dilation and curettage (D&C)

This procedure can be performed in-office or at a surgery center. It involves dilating the cervix, and using a special instrument to remove all of the tissue. You may receive general or regional anesthesia.

What Should I Expect When Recovering From an Early Pregnancy Loss?

Obstetrics, Abnormal Pregnancy, Early Pregnancy Loss, Menopause Center of Los AngelesTo prevent infection, you should avoid vaginal intercourse for 1-2 weeks following the miscarriage. During this time, do not put any objects in your vagina, including tampons and birth control devices.

You should contact us right away if you show any signs of infection, such as:

  • Severe Pain
  • Fever
  • Chills
  • Heavy bleeding (going through two or more pads per hour, for longer than two hours)

Remember that early pregnancy losses are very common. The vast majority of women go on to have normal, healthy pregnancies after their first miscarriage. If early pregnancy loss becomes a pattern for you, please make an appointment for testing to determine the cause and a course of treatment.
