my name is carrie and for the past few years i have noticed a drastic change in my cycle. i have always had irregular periods but nothing like this. when its really heavy, there will be huge clots and i am on it for at least a month if not longer. im really worried because my older sister had a stroke at 28 years old, which is how old i am at the moment. at times it is also brown in color as well.... im really freaked out cause now i have been getting really bad headached and that is the same thing my sister had been complaining about before her stroke!
