Thanks for posting your query.
From the information you have provided,
Your placenta is in the normal position, your
cervix is also normal.
The
amniotic fluid ( around the baby) is less .
Normally its 10-15. 8 is slightly lower.
This can be due to less fluid produced or loss of fluid.
We need to check whether you are losing fluid from the vagina.
The other reason could be growth problem in the baby .
From the values you have provided ,its difficult to comment on the growth.
We have to plot the values on a
growth chart and repeat another scan in 2 weeks to see the interval growth.
Also we need to monitor your blood pressure as
high blood pressure can cause this problem.
All the best, Hope I have cleared your doubts!
