So I tested my self today, 3 days before I was planning on going in for the real test. I used the first void of the morning, it was quite yellow, midstream. I think I tested negative, but the line in the test region was very, very faint. I've attached a picture that you all can evaluate for yourselves.

This leads me to another question - if I'm testing negative at home today, should I just go in for the real test today? Or is it better to wait till Monday? I have this option because it is "up to me" to get the test done.

Thanks
