Your doctor may ask you to rest in bed for 1 to 2 days. The bed rest may stop the bleeding and your pregnancy may continue normally. Special precautions such as stopping exercise, staying off your feet as much as possible, and avoiding sex may be necessary for several weeks. If the bleeding is caused by an incompetent cervix, your cervix may be stitched shut until delivery. If your uterus or cervix is abnormal, your doctor may recommend a long period of bed rest and medications to relax your uterus.
Miscarriage becomes inevitable if the bleeding and cramping continue and the cervix begins to open.
An inevitable miscarriage means that the fetus has died and nothing can be done to prevent the miscarriage. The uterus expels its contents entirely. This is called a complete miscarriage. The miscarriage is incomplete if only part of the contents of your uterus are expelled. In these procedures the cervix is stretched open and tissue is gently scraped or suctioned from the lining of your uterus.
