From yesterday, i was having diziness. It was my second day menstural, so i thought that was the reason. But now a days i am not able to eat properly and i am not feeing hungry, so i did not have my dinner yesterday night. Today morning my temp was normal but i had diziness and i fainted. I am feeling very tired and not able to concentrate. Also i am having diahrrea with severe stomach ache. I am feeling sleepy too often. As my exams are going on, it would be great to get suggestions
