Wow, I can't believe how similar your story is to mine. I've had extremely crazy periods for the past year but it came to a climax about 4 weeks ago when I just started bleeding out of the blue and still haven't stopped. Like you, I have been having lots of clots and lots of times when I think it's finally stopped only to have it come back in a few hours. I went to see my ob/gyn and had some blood tests done and have an ultrasound scheduled. Since I'm only 25 menopause wasn't even something we discussed. It turns out that my thyroid is having some issues that that "might" be the cause of this. I'm very interested to see if they are really going to recommend that you have a hysterectomy or D&C to correct this. I had a D&C a year ago due to a miscarriage and wouldn't want to have to go though that again, and a hysterectomy seems a bit extreme.
Not knowing what the problem is is also driving me nuts. I keep wondering if this is a uterine problem or a thyroid problem or a combination of problems.
The best way I've found to pass the time for the next few weeks is to try and stay positive. I'm trying to watch funny movies, listen to upbeat music, and enjoy spending time outdoors with my children. Best of luck to you and please update us on how things continue.
