The symptoms and the Complications of Placenta previa
Placenta previa, though not a frequent condition, is
most often the cause of painless bleeding in the last
trimester. Since the low-lying placenta is covering
the opening, bleeding occurs when the cervix dilates
even slightly, causing the placenta to pull away. As
the placenta pulls away, there will be sudden vaginal
bleeding, sometimes profuse and with some cramping (but
mostly painless bleeding).
The blood loss is usually bright red coming from the
placenta and is usually intermittent, ranging from light
to heavy with periods of no bleeding. It usually occurs
at the end of the second or the beginning of the third
trimester. Bleeding may continue for a few days and
then comes to a stop on its own, only to start again
a few days or weeks later. In some situations labor
follows suit and in other cases labor precedes the torrential
Once the condition is confirmed via an ultrasound, your
health care provider will suggest the course of treatment,
which will depend on a number of factors. Risks include
blood clots, the need for blood transfusion and infections.
Severe bleeding can cause hemorrhage in the mother and
also lead to fatalistic consequences in mother or baby.
Baby has a high chance of survival if delivery is after
the 36th week. Placenta previa can be dangerous if proper
care is not given in time - any form of vaginal bleeding
should be immediately informed to your doctor.
