*sigh* yes, I also have this trouble. I am on BC and have never had any trouble with it. Since I have been LC, it comes a week early and lasts for a full two weeks. So far, this has happened for three months. I have to say, it's getting old. And expensive...lol....

But, I suppose for the weight loss, it's worth it. I have also heard that it fixes itself, so I am just trying to wait it out....
