Tips for testing during day at work?

Aly

So this is my first month using OPK’s. I’m using the strips and feel like I’m getting close so I want to be able to test twice for the next few days. Only hang up is I work full time 8-4 lunch break 12-1. So I could test during my lunch break, but I work at a very small hospital and so it would be super weird/obvious that something was up if I went to the bathroom with a cup haha, or even a purse. I could definitely sneak a test in my pocket but have no idea how to get something to pee into. Anyone else have to test during work hours and have any tips/tricks?
