| type | risk level | feature |
|---|---|---|
| complete placenta previa | high risk | The placenta completely covers the internal cervical os |
| partial placenta previa | medium risk | The placenta partially covers the internal os of the cervix |
| marginal placenta previa | low risk | The edge of the placenta is close to the internal cervical os but does not cover it |
