TY Burnt Toast for the clarification. So, outside of being absolutely sure of passing with a sub, could the fact I had done strenuous excercise on the morning of my last test have a direct effect on my positive result? I think I effed up by doing that. I had only done one home test prior to that, and it was negative. My new plan is to do 4 or 5 days home test on first void. Also curtailing the excercise like you said. Assuming the hometests being clean, I plan on going to final test natural on my own.
