Peeing in a Cup

This may be a really dumb question but oh well 😜

First morning urine gives the best pregnancy test results. However, my husband often works overnight and gets home at 8:00am, and there's no chance I'm holding it when I wake up 😬😬 He wants to be with me when we see that negative or positive line, so please no suggestions of making it a surprise for him.

Can I pee into a cup as soon as I wake up, and set it aside, to dip the stick into when he gets home? Or would that affect results?
