Dear Sir,
I am 24 years old Lady with slim body structure. My husband went Gulf two months before. Now within one month, I got menses two time with heavy bleeding with brown colour. And I consult a doctor and she advised me that it's because of hormonal changes. There is no problem in ultra sound result and she prescribed for some pills to correct the period , now the period is clear. But now I feel too tired and vomiting two or three time when I take the pills.

Did she say how long to take the pills? I would call, let your doctor know that the pills seem to be making you ill. She may suggest a different sort of pill or she may suggest stop taking them and see if your period continues to be regular from now on without them.
