Finding out about a pregnancy can be an incredibly exciting time for a family. On the other end of the spectrum, a spontaneous abortion can bring about a feeling of true devastation. It may occur through miscarriage, which happens when a pregnancy has yet to reach 20 weeks gestation. Spontaneous abortions may also occur late into the third trimester as well, but when this occurs, there is a better chance of saving the baby’s life. Any child at 24 weeks gestation has at least a small chance of survival.

Spontaneous abortions account for the most common type of pregnancy loss in the world today. Women who are seeking fertility treatments to become pregnant account for the majority of these spontaneous abortions. Many women may not have even realized that they were pregnant when the spontaneous abortion occurs because it can happen so early on.

It should be made clear that a spontaneous abortion is not a conscious choice that a woman makes. It should not be compared to the medical procedure whatsoever.

What Are the Warning Signs of a Spontaneous Abortion?

Women who have back pain that is generally worse than their normal menstrual cycle cramps during the first weeks of a pregnancy should schedule an appointment with their doctor immediately. Other common signs of a miscarriage include bleeding, tissues with clotted materials being expelled from the body, weight loss, and the presence of mucus that is white or pink in color.

A spontaneous abortion isn’t a single event that just “happens.” It must go through several different stages so that the tissues can eventually be expelled from the body. If those tissues remain, then a procedure called a dilation and curettage must be performed to reduce the chances of an infection. Bleeding is common after a spontaneous abortion, so it should be monitored closely by a doctor if it continues on for some time.

Most miscarriages are due to chromosomal abnormalities. There is not much that can be done to stop them from happening. Women can take care of themselves, take folic acid daily, and manage stress to be as healthy as possible. Outside of that, a spontaneous abortion isn’t anyone’s fault at all.
