Welp, that's all she wrote, I ended up taking the test this afternoon and PASSED! Woke up, took some aspirin, diluted for only about 2 hours, did another home test just to be sure, passed that, popped some b-complex, took the test 45 minutes later and passed on the spot!
I think I may have been an exception though, I didn't have to go to a lab to get it done. The test was basically for insurance purposes only, so they just gave me a 5-panel EMIT in-house. Just gave me the cup, sent me to the bathroom, and peeled back the sticker. They actually waited for the results right in front of me, yikes. Good thing everything turned out negative or that could have been a most awkward situation.
Anyway, chalk up one more testimony to dilution/asprin/b-complex. I'm also putting in a good word for the Walgreen's AtHome test, it saved me a little stress for sure.
