get to a doctor and have it checked, don't delay, hope things go well for you:)

i m not a doctor so i can only guess. it is good to see a doctor to see what they suggest.
i started spotting a year ago and i found out i have a small cyst on my ovary. my doctor said they come and go, but sometimes they get big and it has to be removed.
then i started bleeding heavy with large clots. the doctor told me large clots goes with a heavy period. they checked my thyroid, seen if i have cancer, fibroid tumors, low grade infection.
they couldnt find anything so they preformed a hysteroscopy (camera in uterus) and d&c (scraping of the lining of my uterus- it has thickened because of me bleeding for so long.
they diagnosis me with dysfunctional uterine bleeding. that just means that i bleed for no reason, i dont have anything wrong with me.
it could be from me having high blood pressure, gaining 30 pounds in a short amount of time.
but i m on birth control pills to regulate my periods. i m just afraid to get off of it.
