Welcome to ehealthforum.
“Placenta-posterior and lower end covering the internal os” means that the placenta is situated posterior or on the posterior wall of the uterus, and it is extending down to cover the internal os or the inner end of the cervical canal that connects the uterus and the vagina. This is a pretty serious thing. You need to avoid having rough intercourse, as it can lead to bleeding and damage to placenta, and might also trigger onset of miscarriage if bleeding is severe. During labor, it will need to be a planned cesarean section to avoid damage to the placenta and avoid compromise in blood flow to the baby.
Discuss about the delivery and the cesarean section plans with your treating obstetrician. If this is early pregnancy for you, then you can have serial scans later after 2nd trimester to see if the placenta gets ‘pulled up’ in course of the pregnancy due to the growing of uterus into the abdomen as the baby grows.
Take care.

congenital scanning
Hello. My name is Aida and I'm currently in Cebu City Philippines. I am in 20 weeks pregnant now. About 18 weeks and 5 days, I had a congenital scanning and it found out that my placenta posterior is partially covering the internal os. Fetal congenital scan is unremarkable, to repeat scan near term. I really don't know the meaning of this since I am not medically inclined woman. I had 4 times bleeding when I was in Norway and the third time was quite worrisome to me. But it went alright after a week I undergone ultrasound. Most of the days, I feel so very heavy in my stomach and bearable pains and what I only do is just lay down all the time.

Can you give me what tips I have to do and what are the explanations of the result of the congenital scanning? Is there a chance the placenta will change its position?

Take care and hope to hear from you.

Doctor did not say that placenta posterior is a serious problem. But 'extending down to cover the internal os' is a problem!!
