I just got my period today but I have noticed strange things happening. My cramps are 10 times worse than they usually are and when I went and changed my 'pad' I discharged a solid that I don't know what it was (It was like rubber) as well as VERY heavy bleeding. Do you think this could be a miscarriage?

It could have been. They seem to be common; no one knows how common, since many probably go unnoticed.
