I didn't see/process the PT acronym right away so I thought this was a post about sex. I was like, "wow, concentrate as hard as possible? really?"
Yes it will be ok. I've heard of people peeing in a cup then saving it until DH gets home from work in the afternoon. wow (and way to go willpower).
As for the people who said "just take the test," well she said she wanted to take it with DH and can't hold her pee.
