If it's white discharge and it's itchy, then it is probably an infection. However, we cannot say for sure whether she is pregnant or not or if it is indeed an infection because we cannot see her nor can we run tests on her.

First thing in the morning is the best. She can eat and drink normally but she doesn't want to overdrink beforehand because then the urine could be too dilute. If she takes it in the morning or waits a few hours before going, then she should be fine. However, how close is she to her next period? The odds of her being pregnant from possibly some sperm on your hand after you washed it is slim.

By the way, I don't recommend having any sexual contact without some sort of barrier until she gets herself looked at if she is having itchiness, pain, and white discharge. The last thing you'd want is a fungal infection on your mouth or penis.
