i have been having the same white discharge also, i do not know what it is from and i did not know if it was normal or not?
vaginal discharge, as long as its whiteish in color, is perfectly normal. I have had it for as long as I can remember. Whats happening is your body is secreteing all the "garbage" it doesn't need. This is a great thing, althought you may hate it as much as I do. You will come to notice that you are not going to get sick as often or as severe as others will. There is a very small number of women that this happens to, so consider it a blessing. You will definitly have to wear panty liners for, well, about forever...but after a while is becomes quite normal.
as far as the smell goes, everyone has a disctinctive smell. If it is unpleasand or abnormal, I would definitly go to a doctor, just to be on the safe side...
