A clear guide to placenta previa, covering warning signs, diagnosis and delivery planning to keep mother and baby safe.
Treatment usually begins with
Ultrasound Confirmation
Specialist Assessment
Close Monitoring
Delivery Planning
Most cases are managed with monitoring and a planned cesarean delivery at the right time.
You may need this evaluated if...
A placenta previa evaluation is recommended when these signs appear:
- Painless vaginal bleeding in the second or third trimester
- A previous cesarean delivery
- A low-lying placenta noted on an earlier scan
- Carrying twins or multiples
With monitoring and planned delivery, most cases of placenta previa result in a healthy outcome.
What is Placenta Previa?
Placenta previa occurs when the placenta lies low in the uterus and partially or fully covers the cervix, which can affect how the baby is delivered.
Often Found on Routine Scan
Many cases are first identified during a routine mid-pregnancy ultrasound.
May Resolve on Its Own
In some cases, the placenta moves away from the cervix as the pregnancy progresses.
Needs Delivery Planning
A cesarean delivery is usually planned if the condition persists.
Closely Monitored
Follow-up scans track the placenta's position through pregnancy.
Common Symptoms
- Painless bright red vaginal bleeding
- Bleeding that may stop and restart
- Contractions accompanying bleeding in some cases
What Increases Your Risk
A combination of medical, lifestyle and hereditary factors can increase the likelihood of this condition.
How It Is Diagnosed
A structured assessment confirms the diagnosis and helps guide the right treatment plan.
Routine Ultrasound
A mid-pregnancy scan often first identifies a low-lying placenta.
Follow-up Ultrasound
Repeat scans track whether the placenta's position changes as pregnancy progresses.
Transvaginal Ultrasound
A more detailed scan confirms the exact position relative to the cervix.
Delivery Planning Assessment
Later scans guide the timing and method of delivery.
Treatment Approaches
Medical Care
- Activity restriction as advised by your obstetrician
- Avoiding strenuous activity or intercourse if bleeding occurs
- Close monitoring with follow-up ultrasounds
- Hospitalisation for observation if bleeding is significant
Surgical Care
A planned cesarean delivery is typically recommended when the placenta continues to cover the cervix close to the due date.
Treatment decisions are based on symptoms, test results, timing and overall health, not a single test.
Know When to Act
Recognising these signs early and acting promptly is important for the best outcome.
