After my father's death last year, I went through heavy stress and irregular lifestyle. Above all,my periods became light. Even though,I get periods in every 28 -35 days it became very light, and mostly clots. But last month I got it very late,14days. And it was not even periods ,only spotting. But after that I started getting spotting throughout the month. Now,this month,after 28days of my previous month spotting,I got periods but it so heavy now! It's been 7days since I am bleeding heavily. I experience no cramps but now I am feeling weak by seeing heavy bloods and big clots. What is the issue here, please enlighten me.
