Hello
Thanks for writing to us with your health concern.
I would be glad to assist you in interpreting the report.
SIngle fetus means it is a singleton
pregnancy, not multiple babies.
Cephalic means the head, it means that the head is inside the pelvis, this is the normal presentation, as it is supposed to be.
GA 13 weeks, means that the
gestational age is 13 weeks - the pregnancy corresponds to 13 weeks of pregnancy.
Placenta is situated posteriorly, which is also normal.
Normally the placenta should be situated in the upper fundal part of the
uterus.
In your case, it is extending below and is reaching the edge of the
cervix, which is, the mouth of the uterus.
This means that you might spot and bleed, and chances of
miscarriage exist.
Take rest, avoid intercourse and stress.
Take the medications prescribed to you.
More than half of such placentas will migrate upwards as the pregnancy advances, so dont stress out.
All the best
Take care.
