1. If the test is negative, discuss the bleeding and cramping with your health care provider.

2. Worse bleeding (more than one pad per hour)
3. Passage of tissue
4. Fever
5. Anything else that concerns you

With another blood test, your quantitative beta-HCG level may be checked in 48-72 hours. The rise or fall of this level is helpful in predicting the viability or failure of the pregnancy. If the level is falling, then the pregnancy may have ended.

A follow-up ultrasound may be done at some point.

There is no way to predict or prevent a miscarriage. Certain steps can be taken, however, to give your pregnancy every chance to continue to term.

1. Get prenatal care and follow the advice of your health care provider (family doctor, obstetrician, midwife).
2. Avoid alcohol, nicotine, and street drugs , especially cocaine, during pregnancy .
3. Avoid or cut down on caffeine.
4. Control high blood pressure and diabetes.
5. Identify and treat any bacterial and certain viral infections.
