To pee or not to pee...?

Ok, I’m feeling anxious. I have an appointment tomorrow afternoon for a visit with a OB/GYN. My appointment is an hour long and includes an ultrasound. Checking stuff out since I have crazy cycles. Tomorrow will be day 132 of this cycle. Last pregnancy test I took was bfn on October 15. I’ve spotted very lightly most of October. On the slim chance that I’m actually pregnant (we’ve been trying for over two years without anything so far), should I take a cheapy pregnancy test BEFORE my appointment (likely when I get up tomorrow)? Or will they just “discover” a pregnancy if there is one tomorrow?

Maybe that sounds dumb, but I’m new to this part of the journey (aka, seeking professional help with straightening out/checking out my body).
