Period 2 weeks long !

Hello everyone for the past two weeks I’ve had an extremely heavy period, started with major blood clots bright red that lasted for way over a week,about 3 or 4 days ago it then went pink and yesterday it stopped / dried blood but this morning it’s back to a dark red can anyone advice how I make it stop ?? Ive tried pain killers to thin my blood I’m also on the pill there’s seems to be nothing! Thank you x
