I get white fluid before period for a week which create smell and my panty get wet provide a home remedy ?

Discharge: There is a change in vaginal discharge during the cycle, before ovulation it is clear and stretchy to promote sperm movement, toward the beginning and end may be white ,as you noticed, if it has an odor would get checked out at urgent care/gyn as may be bacterial vaginosis /mycoplasma/ureoplasma or yeast ( though that is usually itchy) infection. If getting wet wear panty liners.
