Miscarriage refers to losing a baby prior to the 20th week of pregnancy. About 50 percent of fertilized eggs end as a miscarriage. Many miscarriages occur before a woman even realizes she is pregnant. The reason for a miscarriage may relate to an infection, diseases that existed before the pregnancy, immune system issues in the mother or chromosome issues that impede development of the fetus, notes MedlinePlus. A range of symptoms may indicate a miscarriage is starting.
Vaginal Bleeding
Vaginal spotting or bleeding is a sign a miscarriage may be starting. The bleeding may be sporadic or ongoing. Heavy bleeding may signal that the hormone levels associated with pregnancy are diminishing. The bleeding is sometimes accompanied by vaginal cramping. Bleeding is not always a sign of a miscarriage, however. Each incident will require investigation via a medical appointment.
Vaginal Discharge of Tissue or Pus
Vaginal discharge of clumps of tissue, fluid, such as pus, that may be because of an infection, or what appears to be blood clots may indicate a miscarriage. The discharge may start without any warning or may be preceded by cramping or pain.
Back and Stomach Pain
Pain in the lower back or stomach may be a symptom of a miscarriage. The pain may be strong and sudden, or it may be like cramps. Back and stomach pain may indicate that a pregnancy is becoming problematic.
Fading of Pregnancy Signs
Early in a pregnancy, certain signs arise, including nausea or breasts that seem swollen or tender. If the body starts to feel more normal again before the 20th week of the pregnancy, or if the nausea stops unexpectedly, it may be a sign of a miscarriage.
