I got my period 2 weeks early and it was very heavy and I am now just starting to lighten up. I am on my 13th day. Does anyone know why this is happening or what it could be? :( I have never had it like this. Ask anything if need to...

You need to go to the doctor and have blood drawn. It could be that you are anemic.

Even if I have never had it like that before? Can there be any other reasons?

There can be many reasons, but only a doctor can diagnose it properly.
