Hi, welcome to HCM.
Bleeding during pregnancy
in not a normal. Bleeding at 10th week is possibly due to decreased progesterone
support to foetus. It is most common cause in first trimester.
Your doctor has prescribed susten
tablets which is progestogen containing drugs. It is correct treatment. It has no side effects on foetus. Just follow your doctors instructions , it is correct for better outcome of pregnancy.
Hope I have answered your query.
