Discharge?

Sarah-Jane
I keep getting white creamy discharge for the past 4 days, and today I've noticed quite a lot. There is no odour to it and I'm not itching or anything below. The main thing that is worrying me is the fact that normally this is my time of the month, around the 5th every month I'm due on. I know it's only the 7th but I never have this much wet discharge near/close to a period! What could it be? X
