So, I've been reading up on a lot of different things and I keep coming up on a question I can't find the answer for.

Say a woman has a milky white discharge that doesn't smell at all...

(typicaly yeast infections smell fishy and other infections tend to be a yellow or green color.)

So, normal or abnormal?

It can be normal if it is during her ovulation.

Normal. It just sounds like ovulation :)
