Summarize the following:
The spotting or bleeding can be normal, but it may also be a warning sign of complications with the pregnancy, such as a miscarriage or an ectopic pregnancy. Additional feelings of pain, fatigue, or dizziness warrant further evaluation by your doctor. Heavy bleeding between your periods, and even during your period, can be an indicator of complications, many of which are easily managed. Contacting your gynecologist is the first step in determining the cause of the heavy bleeding and discovering possible treatment options. Whether you are taking continuous hormone therapy, cyclic hormone therapy, or not taking hormone therapy at all, episodes of unexpected bleeding are not normal. Contact a doctor if unexpected bleeding occurs. The risk of cancer increases by about 10% in postmenopausal women that experience vaginal bleeding. If you go as long as 90 days without having your period, then contact your doctor. Stop using tampons and contact your doctor immediately if you develop a fever, muscle aches, diarrhea or vomiting, dizziness or fainting, an unexplained sunburn-like rash, sore throat, or notice redness in your eyes. Spotting can be caused by conditions or illnesses both unrelated and related to women's health issues. Either way, your doctor can help to rule out other conditions or illnesses. The use of certain medications like corticosteroids, blood thinners, and even antidepressants have been linked to episodes of spotting. Thyroid disease and diabetes are also possible contributors to spotting between your periods. Women's health conditions that may be causing the abnormal bleeding episodes can include uterine fibroids, uterine polyps, polycystic ovarian syndrome, endometriosis, bladder or vaginal infections, and cancer. Abnormal pap tests and infections like gonorrhea and chlamydia can also cause abnormal spotting. Seek medical attention as soon as possible if you continue to have abnormal bleeding or spotting.

Summary:
Contact your doctor immediately if you are pregnant and bleeding. Seek medical attention if you experience abnormal bleeding accompanied by other symptoms. Watch for episodes of heavy bleeding. See your gynecologist as soon as possible if you are postmenopausal and bleeding. See your doctor if you stop having a period. Contact your doctor if you use tampons and develop symptoms.
