Lol at the begging cath.
The reason I think you should do another today is this: you have a line so the idea you might be preggo is already in your head. If it is an evap, which I don't think it is, then if you tested again and nothing today, you'd know you weren't and wouldn't spend the next 24 hours thinking you are. And that line on your IC was clear as day,and would be on a frer. Plus if you poas today, that's one day earlier you see your GP, and one day earlier you get proper meds x
