What should you know about placenta previa type 2 anterior and posterior?

Anterior means the placenta is attached to the front wall of the uterus; posterior means it is attached to the back wall. Type 2 is a position label used in some classification systems for a placenta close to the cervix. The scan report should state whether the placental edge approaches or covers the cervical opening.

The front-versus-back direction does not by itself tell you whether vaginal birth is possible. As the uterus grows, the relationship between the placenta and cervix can change. Vaginal bleeding can occur and may be painless, so absence of pain does not make bleeding safe to ignore.

Ask the maternity team to explain the measured placental edge and the timing of the next scan. Follow their advice about sex, vaginal examinations, exercise and travel; restrictions are individual and particularly relevant after bleeding. Keep a plan for reaching the hospital and carry your antenatal information when away from home.

A Growth Scan may be included in follow-up when your clinicians want to assess fetal growth. If the placenta remains too close to the cervix, the team may recommend Caesarean Section and explain the timing and safety arrangements.

Report any vaginal bleeding to your maternity unit straight away, whether it is spotting, bright red blood or bleeding that has stopped. Emergency symptoms include heavy bleeding, faintness, severe abdominal pain, contractions or reduced fetal movement. Use a pad rather than a tampon, avoid driving if unwell and follow the hospital’s instructions while help is arranged.

Ask: Is my placenta anterior or posterior, and how close is its edge to the cervix? Does type 2 mean it overlaps the opening in my report? When is repeat imaging needed? What should I avoid? If bleeding occurs, where should I go? How would the placental position affect a Caesarean Section or labour plan?
