As long as you don't smell like bread, you're fine.
The extra discharge comes about with ovulation unless you're excited, but that's a bit different-it's thinner.
I shave completely and since doing so have noticed less odor from sweating, etc. than before. I only use cotton undies or cotton lined ones. Panty liners are fine for the last days of a period, but I have found them to hold odor-and the scented ones are worse.
I will comment that if your pants are so tight that they're riding INTO your crotch and therefore picking up odor, you're wearing the wrong size or you're a glutton for punishment. Tight pants are NOT good healthwise and really, we don't need to see you split in half and your outer lips trying to escape their confines...save that for the SO. (Not to mention that even the skinniest girls in very tight pants get that flesh over the top and that's just EW)
