Bleeding after receiving a positive IVF pregnancy test is surprisingly common and affects approximately 30-40% of pregnancies in the first trimester. While any bleeding can feel alarming after the emotional and physical investment of in vitro fertilisation, it does not automatically indicate a problem, but it is important to inform your IVF Centre so you can be guided on the next steps and monitoring.
Reasons - Why Does The Bleeding Occur?
Understanding the causes can help you distinguish between normal spotting and situations requiring medical attention. If you are unsure about what you are seeing, your Ivf doctor can help you interpret the symptoms and decide whether you need a scan or medication adjustment.

Subchorionic hemorrhage
Also called subchorionic hematoma or subchorionic bleed, it affects between 1.3% and 62% of pregnancies. Blood collects between the uterine wall and the gestational sac when the placenta partially separates. The bleeding can range from light spotting to heavier flow and may appear pink, red, or brown.
The progesterone supplementation you receive during IVF can cause cervical sensitivity. This makes the cervix more prone to light bleeding after physical examination, sexual intercourse, or vaginal ultrasounds. These hormonal changes also increase blood flow to the reproductive area.
Cervical and endometrial polyps
It may bleed more easily during pregnancy due to hormonal changes. While generally benign, they can bruise and cause spotting during early pregnancy.
Regarding how much bleeding is normal after IVF:
Light spotting or discharge that’s pinkish or brownish is typical. You might occasionally see small amounts of bright red blood that stops on its own. However, heavy bleeding that soaks through a pad within an hour requires immediate medical attention.
The key factors affecting bleeding in early pregnancy include your age, the timing of detection, and the size of any hemorrhage present.
When Should You Be Concerned?
While light spotting after a positive IVF pregnancy test is often normal, certain symptoms require immediate medical attention. Understanding the warning signs helps you respond appropriately when complications arise.
Heavy bleeding with clots is always a reason to contact your clinic. If you’re soaking through a pad within an hour or passing large clots, this could indicate a miscarriage or a severe subchorionic haematoma. Don’t wait to see if it improves on its own.
Severe cramping accompanied by bleeding warrants urgent evaluation. Intense, sharp pain on one side combined with bleeding may signal an ectopic pregnancy, where the embryo implants outside the uterus. This condition is dangerous and requires immediate medical care.
Severe cramping accompanied by bleeding warrants urgent evaluation. Intense, sharp pain on one side combined with bleeding may signal an ectopic pregnancy, where the embryo implants outside the uterus. This condition is dangerous and requires immediate medical care.
Be alert for these warning signs
Bright red blood flowing like a period
Severe abdominal or pelvic pain
Fever above 38°C
Passing tissue or large clots
Dizziness, fainting, or shoulder pain
If you’re passing solid tissue along with blood, this could indicate a miscarriage or, rarely, a molar pregnancy where abnormal tissue develops instead of a healthy embryo. Collect any tissue you pass if possible, as your doctor may want to examine it.
Contact your IVF clinic immediately if you experience any of these symptoms. They may arrange an ultrasound scan or blood tests to assess your hormone levels. Early intervention can sometimes prevent complications, and prompt diagnosis ensures you receive appropriate treatment. Your medical team is there to support you through any concerns during this critical time.
Conclusion
Bleeding after a positive IVF pregnancy test can feel alarming, but it does not automatically signal a problem. Light spotting or pinkish-brown discharge often indicates normal implantation bleeding as the embryo attaches to the uterine lining.
Many women experience some form of bleeding during early IVF pregnancy, with studies showing it occurs in approximately 30-40% of cases. Most episodes resolve naturally without leading to pregnancy loss.
Each pregnancy develops differently, and the presence or absence of bleeding does not predict your outcome. Some women experience various symptoms whilst others have none at all. Trust your medical team’s guidance and report any changes that concern you. Your doctors understand the unique aspects of IVF pregnancies and can provide personalised advice based on your specific situation.
