Thank you for your query.
As your ultrasound
is normal, you should not worry for now.
Spotting anytime in the pregnancy
obviously bears a risk for miscarriage
, however you have been prescribed the correct pregnancy support.
However, if the bleeding is heavy or with cramps and pain, chances of miscarriage are very high.
You should take the prescribed medication, take adequate rest, avoid stress
, strain, lifting heavy weights , jerky motions and sexual activity for the time being.
