It is crucial to seek medical attention if you experience any vaginal bleeding during pregnancy.
Causes of First Trimester Vaginal Bleeding
Several factors can contribute to vaginal bleeding in the first trimester (up to 13 weeks of pregnancy). These include:
- Implantation Bleeding: This occurs when the fertilized egg implants in the uterine lining, typically around 6-12 days after conception. It’s usually lighter than a normal period and may be mistaken for a light period.
- Miscarriage: A miscarriage, or spontaneous abortion, is the loss of a pregnancy before 20 weeks. Bleeding, often accompanied by cramping, is a common symptom. Mayo Clinic – Miscarriage
- Ectopic Pregnancy: This occurs when the fertilized egg implants outside the uterus, most commonly in the fallopian tube.Ectopic pregnancies are life-threatening and require immediate medical attention. symptoms include abdominal pain and vaginal bleeding.

- Subchorionic Hemorrhage: A collection of blood between the chorion (the outer membrane surrounding the embryo) and the uterine wall.Frequently enough resolves on its own, but can cause bleeding.
- Molar Pregnancy: A rare complication where abnormal tissue grows inside the uterus rather of a healthy fetus.
- Cervical Polyps or Ectropion: These benign growths on the cervix can cause bleeding, especially after intercourse.
- Infection: Certain infections, such as sexually transmitted infections (STIs), can cause vaginal bleeding.
Evaluation and Diagnosis
When a pregnant individual experiences vaginal bleeding, a healthcare provider will typically perform a thorough evaluation, which may include:
- Medical History: A detailed review of the patient’s medical history, including previous pregnancies, medical conditions, and medications.
- physical Exam: Including a pelvic exam to assess the source of bleeding.
- Blood Tests:
- hCG Levels: Human chorionic gonadotropin (hCG) levels are measured to assess the viability of the pregnancy.
- Blood Type and Rh Factor: to determine if Rh-negative individuals require rh immunoglobulin.
- Complete Blood Count (CBC): To check for anemia.
- Ultrasound: A transvaginal ultrasound is often used to visualize the pregnancy, confirm its location, and assess fetal heart activity. radiologyinfo – Ultrasound in Pregnancy
