What causes a miscarriage?
Most miscarriages happen because the fertilized egg in the uterus does not develop normally. A miscarriage is not caused by stress, exercise, or sex. In many cases, doctors don't know what caused the miscarriage.
The risk of miscarriage is lower after the first 12 weeks of the pregnancy.
What are the common symptoms?
Common signs of a miscarriage include:
* Bleeding from the vagina. The bleeding may be light or heavy, constant or off and on. It can sometimes be hard to know whether light bleeding is a sign of miscarriage. But if you have bleeding with pain, the chance of a miscarriage is higher.
* Pain in the belly, lower back, or pelvis.
* Tissue that passes from the vagina.
