We need advise from good Doctor, what is the solution she’s taking the medicine for vomiting or just like that. i dont want to harm my babay for taking non specified medicine.

Nausea and vomiting in pregnancy is called morning sickness. Morning sickness usually goes away by 3-4 months of pregnancy. But in some cases, it can last well into a pregnancy.
Soak 8-10 almonds overnight, and next morning peel off the skin and eat. For more details checkout below link:
