Placenta previa is a pregnancy complication where the placenta covers part or the entire cervix during the last month of pregnancy. This can be very dangerous as it can lead to very heavy bleeding during delivery.
Placenta previa is quite common in the early stages of period, usually before week 20 but by the third trimester, only in about 1 out of 200 pregnancies is placenta previa present as the condition would have resolved on its own.
As the uterus expands, it pulls up the placenta. Also, the placenta tends to move towards a richer blood supply in the upper part of the uterus, therefore the positioning of the placenta becomes normal.
Certain women do have a greater risk of the condition and they include older women, women who have had children and women who have had a previous cesarean section.
The cause of placenta previa is not exactly known and therefore there is no known way to prevent the condition. In other words, a woman does not have any control over where the placenta attaches on her uterus.
Early diagnosis can make a big difference as it will ensure that the woman receives the care and treatment she needs. Here are some of the symptoms of placenta previa. If you experience any of these symptoms, you should see your doctor right away:
- Vaginal bleeding, which may be light or severe after the 20th week of your pregnancy. The bleeding may come and go
- Abdominal pain
- Uterine contractions
- Bleeding after intercourse
