Whitish vaginal discharge once in a while especially after going to the bathroom number 2. got pap smear the results came back normal. what can it be?

Yeast or BV: The discharge you are describing is a common symptom of either yeast infection (candida) or bacterial vaginosis. Both are very common and treatable. This could also be a sign of a sexually transmitted infection (esp if you have had sex without a condom), your provider may or may not have tested for these with the pap. Follow up with the provider who did the pap for definitive diagnosis/treatment
