As long you're washing your clothing properly and often enough you won't get any infection, bad smells or other bad things. It's important that you're changing clothes often enough. When it comes to underwear you should either only use it once time and then wash it or you can use it 2 - 3 days in a row where you're using pantyliner due vaginal discharge.
