There are some factors that may contribute to miscarriage.
Women who have miscarriages can and often do become pregnant again, with normal pregnancy outcomes.
Signs of a miscarriage can include:
Although vaginal bleeding is a common symptom when a woman has a miscarriage, many pregnant women have spotting early in their pregnancy but do not miscarry. But, pregnant women who have symptoms such as bleeding should contact their health care provider immediately.
Women who miscarry early in their pregnancy usually do not need any treatment. In some cases, a woman may need a procedure called a dilatation and curettage (D&C) to remove tissue remaining in the uterus. A D&C can be done in a health care provider’s office, an outpatient clinic, or a hospital.
