Implantation bleeding or early period? No pic.

I am due on, on the 2nd Dec, but started to bleed a pinkish colour late last night so 2 days early (small amount) and it has continued to today but more volume. But as the day has gone on its got a bit darker (more red). I normally bleed very heavily form the start and I am pretty regular. I also can't stop weeing which is really not like me I normally only go 3ish times a day. any advise welcome. X
