Dear doctor, Actually in recent past I am experiencing that just a week before my period I feel extreme emotions and difficulty to focus which is causing havoc in my relationship and my studies. Even after period I find myself having heavyness in head and find it difficult to study. I feel I'm having hormonal issues, shall I have regular birth control pill to control my issues. Also in that case can you suggest some affordable pill which I can use on daily basis without having any side effect.
