Placenta praevia (placenta previa AE) is an obstetric complication in which the placenta is attached to the uterine wall close to or covering the cervix. It can sometimes occur in the later part of the first trimester, but usually during the second or third. It is a leading cause of antepartum haemorrhage (vaginal bleeding). It affects approximately 0.5% of all labours. Source: Wikipedia
Placenta previa can be divided into four types, of which the first two are the most common:
1. the placenta is positioned low in the womb, but the baby can still be born vaginally.
2. the lower edge of the placenta touches the opening of your cervix, but does not cover it, so the baby can be born vaginally.
3. the placenta partially covers the opening of your cervix. The baby will need to be born by caesarean section.
4. the placenta completely covers the opening of your cervix. The baby will need to be born by caesarean section.
