The term "spontaneous abortion" or the initials SAB are often used to describe a pregnancy that ends on its own within the first 20 weeks of gestation. According to the American Pregnancy Association, most miscarriages occur during the first 13 weeks or first trimester of pregnancy, and the chances of miscarriage range from 10 to 25 percent depending on a woman's medical history and age. There are several signs to indicate that a miscarriage may be occurring during the first trimester. If you experience any of them it is important to seek medical attention immediately to make a proper diagnosis and determine if any treatment is necessary.
Pain
Pain associated with first trimester miscarriage can include mild to severe back pain. It can be likened to lower back pain that often accompanies cramps during menstruation, but is usually more intense. In fact, Pregnancy-Facts.com states that most early miscarriages are mistaken for a heavy menstrual period. Painful contractions in your lower abdominal area, occurring anywhere from five to 20 minutes apart, can also occur.
Vaginal Discharge, Spotting & Bleeding
Many women who experience a miscarriage during the first 13 weeks of pregnancy experience an unusual discharge that is pink-tinged in color. The American Pregnancy Association reports that brown or bright red blood can also occur, with or without cramps, although many pregnancies that do not end in miscarriage experience some sort of bleeding. The flow of this blood can range from light spotting to heavier bleeding. The discharge can even resemble clotted material or tissue.
Decreased Pregnancy Signs
A decrease in pregnancy symptoms, often indicating a decrease in pregnancy hormones, can also occur with a first trimester miscarriage. Many women report that they feel less nausea or breast tenderness when they suspect a miscarriage has occurred or is imminent.
