Thanks for posting your query.
You need to take healthy diet which is of utmost importance.
Particularly diet rich in iron like dry fruits like almonds, dry grapes, cashew.
Even peanuts are very helpful and more fruits and vegetables and diary products like milk and curds.
Also be stress
free and drink more water and see that you are not loosing more blood through your cycles or through any other source like bleeding piles.
Hope I have answered your query.
Wishing you good health.
