You know UT21, the test lines I had look like your day 16 & 17. Faint but visible, thats why I got a little too confident. However, the difference between you and me, is you have self tested about 5 times to my only 1. that's why I believe the pros, when they say any faint line is a negative regardless. Again, my only concern is the posts on the web about abstaining from excercising heavily at least 48 hours prior to the test. It's like I want to stop the sweating now, and since I am unsure, sub the test out with quickfix 5.7.
