I'm a 19 year old girl. I started having periods from the age of 14. It was all normal for few years but from last two years I'm facing the problem of irregular periods. I get periods in 3-4 months. There is no fixed date, I can get them anytime. I have proper diet and is a healthy person but don't know why suddenly this missing of periods? I consulted two different doctors, one homopethic doctor, he has given me medicine which I'm taking thrice everyday as recommemded by him but I feel it is of no use. I even consulted a gynachologist a year back, she didn't give me any medicine saying it is normal. But I know this is not right, something is defenetly wrong with me. Can someone tell me whether it is actually normal or there can be anything serious which I need to take care of?
