Oh, I didn't know fluids only helped on the day of. And no, it wasn't my first urination. I have another one that I just ran out to buy. It's a different brand - Quickscreen. I'll use it first thing in the morning. Would it be better to take my actual U/A tomorrow evening after I have drank fluid and used the bathroom all day or wait til Wednesday morning. Extra time would be good, but I know first thing in the morning isn't a good idea. Thanks!!
