5 Reasons for Spotting After a Positive Pregnancy Test

Early pregnancy is a time of rapid changes, and spotting after a positive pregnancy test can be alarming. While it’s natural to worry, spotting isn’t always a cause for concern. In this article, we explore five possible reasons for spotting during early pregnancy and what you should do next.

1. Implantation Bleeding

Implantation bleeding is a common cause of spotting after a positive pregnancy test. It occurs when the fertilized egg attaches to the uterine lining, typically 10 to 14 days after conception.[1] This light bleeding or spotting is usually pink or brown and lasts a few hours to three days.[2] In a healthy pregnancy, implantation bleeding resolves on its own without medical intervention.[3] If you’re unsure whether your spotting is implantation bleeding, speak to your doctor as soon as possible.

2. Vaginitis

Vaginitis, an infection or inflammation of the vagina, can cause spotting, discharge, or irritation.[4] Hormonal changes during pregnancy may increase your risk of vaginitis, which can lead to spotting after a positive pregnancy test.[5] Untreated vaginitis during pregnancy may increase the risk of preterm labor[6], so prompt treatment is essential. Speak to your healthcare provider about pregnancy-safe medications and treatment options.

3. Cervical Polyps

Cervical polyps are small, benign growths on the cervix that can cause spotting after a positive pregnancy test.[7] While rare during pregnancy, they may lead to light bleeding, especially after intercourse or a pelvic exam. Your doctor may monitor or remove polyps depending on their size, location, and your specific condition.[8] Most cervical polyps are harmless, but they may need to be tested to rule out abnormalities.

4. Molar Pregnancy

A molar pregnancy is a rare condition where a noncancerous tumor forms instead of a healthy placenta, leading to pregnancy loss.[9] Spotting or bleeding in the first trimester is a common symptom.[10] There are two types of molar pregnancies[11]:

• Partial Molar Pregnancy: Two sperm fertilize one egg, forming an abnormal placenta and embryo that cannot survive.
• Complete Molar Pregnancy: An empty egg is fertilized, forming abnormal placental tissue with no embryo.

Thankfully, most women who receive treatment for their molar pregnancies don’t experience any further complications.[12] Your risk for future miscarriage does not increase, but you are at a slightly higher risk of another molar pregnancy.[13] Additionally, you will need to receive regular follow-up care to monitor your risk for cancer.

5. Early Miscarriage or Ectopic Pregnancy

Spotting after a positive pregnancy test can sometimes indicate an early miscarriage[14] or ectopic pregnancy.[15] Miscarriage symptoms may include cramping, lower back pain, or passing tissue.[16] An ectopic pregnancy occurs when a fertilized egg implants outside the uterus, often in a fallopian tube, and may cause pelvic pain, shoulder pain, or light bleeding.[17] Ectopic pregnancies require immediate treatment, as they cannot continue and may become life-threatening if the fallopian tube ruptures.[18] Treatment options include medication (methotrexate) or surgery.[19] If you experience severe pain or heavy bleeding, seek emergency care immediately.

When to Seek Help

While spotting after a positive pregnancy test is often normal, certain symptoms may require immediate medical attention:

• Heavy bleeding or clotting
• Severe pelvic or shoulder pain
• Fever or dizziness

Contact your healthcare provider or visit the emergency room if you experience these symptoms.
