First is you should confirm pregnancy... There are chances to miss period without being pregnant...it may occur in women who have anemia i.e low haemoglobin levels,diabetes or thyroid problems. It is also common in women with high levels of a protein called prolactin in their blood...it can be the side effects of certain drugs like oral contraceptives,antipsychotics,antiepileptics...it may be due to poly cystic ovarian disease as well... So I would suggest you to consult nearest gynecologists for detailed clinical examination and evaluation they will do the needful.

Hello, Has she got a urine pregnancy test done? If not then get a urine pregnancy test done to rule out pregnancy. If the result is negative then there is nothing to worry and it might be due to factors like stress only. So wait for her next periods to come. If the result is positive then visit a gynecologist for further evaluation and management and follow the medication course as prescribed.
