Kind of a weird question šŸ˜†

Lillaya ā€¢ TTC #1 - Let's get it on!

So I think this morning I got my BFP! I need to run out and get more tests but I wanna use them with the best urine. I wanna use 2nd morning urine, but I dont think I can hold that until I go out and come back. Would I be able to pee in a cup, and leave that till I could back, or would a hold later in the day work too? I'm just freaking out and i really want to test with a digital, but give it the best chance show.
