Hi I can fully understand your worry.
Before starting this medication blood test for Vit D3 levels and
Calcium have to be done... Ae they done.
Also if baby is otherwise standing by support I think don't worry.
But there are many more questions we need to ask to be sure that you don't need to worry.
You may initiate a direct one to one consult for same.
