Is bleeding during pregnancy always dangerous?
Vaginal bleeding during pregnancy is relatively common, especially in the first trimester, and it does not always mean pregnancy loss. However, the cause cannot be diagnosed from colour or amount alone. Report any bleeding during pregnancy to your obstetric care provider.
Gestational age, volume, duration, colour, and associated pain, dizziness, fever, contractions, or watery discharge all matter.
What causes bleeding in early pregnancy?
Light spotting can occur because the cervix is more sensitive, including after intercourse or an examination. Other possibilities include a subchorionic haematoma, threatened miscarriage, pregnancy loss, or ectopic pregnancy.
Ultrasound can check whether the pregnancy is inside the uterus, whether an embryo and heartbeat are seen, whether measurements correspond to dates, and whether a haematoma is present. At a very early stage, one scan may be inconclusive; repeat ultrasound and serial blood hCG may be required.
Bleeding in the second or third trimester
Later bleeding can be related to cervical change, placenta previa, placental abruption, or the onset of labour. New third-trimester bleeding needs urgent assessment even when it is painless. If placenta previa is possible, a digital vaginal examination should not be performed until the care team has assessed placental location.
When should you seek emergency care?
- Heavy bleeding, rapid pad saturation, or large clots;
- Severe or one-sided abdominal/pelvic pain, or shoulder-tip pain;
- Dizziness, fainting, marked weakness, or shortness of breath;
- Fever, chills, or foul-smelling discharge;
- Regular contractions or suspected leakage of amniotic fluid;
- Reduced fetal movement later in pregnancy.
How is the cause investigated?
The clinical team assesses your general condition, blood pressure, timing, and amount of bleeding. Tests may include ultrasound, a full blood count, blood group and Rh status, hCG, and other investigations. An Rh-negative patient may need assessment for anti-D prophylaxis.

What should you avoid doing?
Do not wait several days to see whether bleeding stops without informing your clinician. Do not self-prescribe hormones, haemostatic medication, or painkillers. Use a pad—not a tampon—to observe the amount, and record the colour, duration, and associated symptoms.
Ultrasound assessment with Lana Ezieshvili
When bleeding occurs, timely ultrasound can help guide important decisions. Radiologist Lana Ezieshvili assesses pregnancy location and development, fetal heartbeat, any haematoma, the cervix, and placental position according to gestational age.
If you are stable and your clinician recommends imaging, book an appointment with Lana Ezieshvili. For heavy bleeding, severe pain, faintness, or rapid deterioration, do not wait for a scheduled scan—seek emergency care.
