is discharge when periods due normal?

[babyangelbean20315]

My period is due yesterday /today but I'm getting white discharge and so far no sign of mother nature's annoying friend obvz ttc but trying not to think about it, this is got me tho and I'm not sure if this is a sign or if it a good or bad or just normal ? I have had strange signs this month for ovulation and everything when usually I have no idea so I'm jus a bit puzzled , don't want to talk to Dr until I am 3 days late...
