Thanks for your query at DoctorSpring.com
This condition is called threatened abortion.
There is no obvious reason but there is a small risk of abortion, hence bleeding and spotting.
Taking the injections and rest will help to avoid more bleeding and an actual miscarriage.
Double marker is done to rule out abnormalities in the baby.
NT scan also does the same.
Point no.2 and 3 please elaborate more as it is not clear what tests you have mentioned.
All the best
Please feel free to discuss further.

3.rule out anamolles
doctor can you plz explain above terminology in (2) and (3) questions..
BIophysical profile is done to know if the baby is alright and the fluid surrounding it is normal in amount.
Rule out anomalies is not a name of any specific test.
Please upload the doctors prescription if you need more clarifications.
