Hi. I am 21 years old and I am not sexually active. Recently, on my 4th day of period, I had a fat tissue like substance getting discharged from my vagina. It was 3-4 inch long, pale white in color with blood cloths in between. I even had a lot of pain the previous night. Can you please help me in knowing what this thing is. I am really tensed and scared thinkng it might be a cancer or something.
