A threatened abortion or miscarriage are the same condition. A patient may present with vaginal bleeding or cramping in early pregnancy, but an ultrasound will show a live fetus (baby) and the patients cervix will be closed. The majority of these patients will continue to have a normal pregnancy, but some will progress to complete miscarriage.
Your doctor may ask these questions to check for this disease:
A specialist typically needs to confirm the diagnosis. With a closed cervix and normal fetal heart beat, they will generally recommend some form of rest and avoidance of sexual activity till things stabilize. Occasionally a medication such as progesterone may be prescribed.
