Glad to help!
Another thought. Any possibility that you could have been pregnant? When I was trying to have my two kids, I noticed that I kept have periods that were a few days late and unusually heavy. My doctor said they were probably pregnancies that self aborted because something was wrong. These spontaneous abortions are really common, something like half of all pregnancies end this way. Most people don't even notice it happened because the person is basically pregnant for 2 weeks or even less. Anyway, a spontaneous abortion could also give you an unusual period. Again, nothing to worry about (well, I should say, depending on your plans

).
But, yeah, I wouldn't worry.
