Hi!
I had gone through your query and understand your concern.
Placenta previa is the attachment of the placenta to the wall of the uterus in a location that completely or partially covers the uterine outlet (opening of the
cervix).
Bleeding after the 20th week of gestation is the main symptom of placenta previa.
An
ultrasound examination is used to establish the diagnosis of placenta previa.
Placenta previa is the most common cause of painless bleeding in the later stages of
pregnancy (after the 20th week).
Because the placenta is rich in blood vessels, if it is implanted near the outlet of the uterus, bleeding can occur when the cervix dilates or stretches.
This repeated bleeding are the cause of her
anemia (low RBC) and low platelets.
I suggest you to consult a Obstetrician and to be under medical attention until delivery.
The doctor will advise you how to proceed in the future when you see that something is going wrong.
Hope I was able to help you.
Take care.
