Bleeding in Early Pregnancy: What’s Normal, What Isn’t, and When to Seek Care
Bleeding in Early Pregnancy: What’s Normal, What Isn’t, and When to Seek Care
Experiencing any amount of vaginal bleeding during pregnancy may trigger fears of miscarriage or something going wrong, especially if you’ve had prior pregnancy loss. If you’re feeling scared or concerned after noticing bleeding or spotting during early pregnancy, know that you are not alone.
“Bleeding or spotting in early pregnancy is very common, and a lot of people will experience it,” says Jennifer Kaiser, MD, an OB/GYN and director of the Early Pregnancy Assessment Clinic (EPAC) at University of Utah Health. “In some studies, it’s reported in up to 40% of early pregnancies.”
Monitoring Symptoms
While bleeding during the first trimester is common and doesn’t always mean something is wrong, it’s always OK to call your doctor.
“I really want to reassure people that if you’re worried about any bleeding or spotting, you should have it evaluated—that’s what we’re here for,” Kaiser says. “We’re never going to feel like it was a waste of time. No matter what it is, we want to be here to offer that open, non-judgmental care.”
Paying attention to your symptoms—such as heaviness of flow and accompanying pain—can help your care team decide next steps.
Am I Spotting or Bleeding?
Spotting
- May be brown, light pink, or red
- A few drops are noticeable on a panty liner or when you wipe
- Doesn't fill a pad or liner
Bleeding
- Looks like period blood
- A heavier flow requires a pad
- Fills or soaks through a pad in 3 to 4 hours
When to Seek Immediate Care
Some light cramping is normal in early pregnancy and usually feels like minor period cramps. However, if the cramping is accompanied by heavy bleeding or has the following red flags, seek care immediately:
- Severe pain or cramps that get progressively worse
- One-sided abdominal pain
- Fever, dizziness, or chills
- Shoulder pain
Possible Causes of Early Pregnancy Bleeding
Bleeding in the first trimester can happen for many reasons. While some are normal and harmless, others may require immediate medical attention.
Common, Usually Not Dangerous Causes
- Implantation bleeding: When the fertilized egg implants into the uterine lining, it can cause light spotting. Some women mistake this for their period because it typically happens around the time their period would begin.
- Cervical changes: Increased blood flows to the cervix to prepare it for pregnancy, and delivery makes it more sensitive. Light bleeding can occur, especially after sex or a pelvic exam, or with a bacterial infection.
- Subchorionic hematoma (hemorrhage): This occurs when blood collects between the uterine wall and the amniotic sac. It typically happens in pregnancies that are between 10 and 20 weeks’ gestation but can also be seen in pregnancies less than 10 weeks’ gestation. If small, the hematoma usually resolves on its own and doesn’t lead to any complications. Large subchorionic hematomas do have an increased risk of miscarriage.
More Serious Causes
- Miscarriage: Vaginal bleeding from an unexpected pregnancy loss can be light or heavy and include blood clots. Cramping is often stronger than normal period cramps. Seek care immediately if you are soaking through two pads in one hour, are in severe pain, or have dizziness.
- Ectopic pregnancy: This occurs when a fertilized egg implants outside the uterine lining, most commonly the fallopian tube. This is a medical emergency and can be life-threatening if the tube ruptures. Seek emergency care if bleeding comes with severe, one-sided abdominal pain, dizziness, or shoulder pain.
Seeking Support During a Scary Time
If you are experiencing any bleeding during early pregnancy, you can always call your doctor for reassurance.
The Early Pregnancy Assessment Clinic (EPAC) at University of Utah Health offers non-judgmental pregnancy care for early pregnancy concerns, including:
- Evaluation of first-trimester bleeding
- Follow-up care based on your specific condition and needs
- Pregnancy loss support
- Social work and behavioral health resources
“One of our goals for EPAC is getting people into the clinic quickly because we know it can be a scary time,” Kaiser says. “We also prioritize being really clear with people about what we think is going on. I never want my patients leaving EPAC to feel like they don’t know what we think is happening, what the next steps are, or that it was a one-and-done visit.”
While bleeding during early pregnancy is common, know that your care team is always happy to evaluate what might be causing it and will support you along the way.
