Continous bleeding. From my diet?

Greetings doctor, I went on road trip to ujjain a couple of months back and while returning back on 12 oct experienced dirty liquid and wetness, n after approximately a week my periods started again which was bfore time, Since then i am bleeding and its been 2 months.. from last 2-3 days its bleeding heavily. Kindly let me know what could be the cause ? If i need to taje any precautions? Whats medical tests should i undergo? If i need to Take particular diet or remove something from my diet? I will be 22 nxt month, very much worried. Last year in march/april i got one of the tests which showed the volume of ovaries, it should have been 4cc bt mine was 9cc and 13 cc. Is it a reason to worry Please guide me, i am very much worried about my health and future. I do not know any gyne. Looking forward to get the best advice and guidance from you. Thank you.
