Maybe a silly question!

🎀Michelle🎀 • I`m a 25 year old mommy of a perfect son and a beautiful daughter! I am pregnant with baby number 3 due Feb 8!
So this morning when I woke up and my pregnancy tests had not been delivered yet! So of course I had to use the restroom! They are now in there way and will be here this afternoon! If I hold my urine until they arrive will this give the same affect as a FMU? Also does the kind of cup I use to dip matter???
