What does it mean if you get your Period every month but start bleeding about a week after that lasting for about 4 days and it starts again the week after that?

It probably means that your hormones are a bit off. If you are on the birth control pill you may want to arrange with your doctor to be put on a different dosage which will most likely help with this. If you aren't on it, plan a consultation with your doctor anyways, you don't deserve to go through all of that!
