• Fever
• Pelvic pain or severe cramps

Bleeding during pregnancy is more likely to be serious if the bleeding is moderate to severe or occurs with lower pelvic pain. These symptoms may be caused by an infection, ectopic pregnancy, miscarriage, or another serious problem.

If you know that you are pregnant and you have vaginal bleeding, call your doctor right away to discuss your symptoms.
