Unfortunately, missed bleeds can happen after the adjustment period as well. I don't know why they indicated that it was just a settling in thing.
The 19 day wait is to allow for your body to build up enough of the hormone. People get positives as early as 10 days. To decrease the chances of a false negative, test with your first pee of the morning--it will be the most concentrated. Also know that with a healthy pregnancy, hCG levels double every two days, so each day you wait the likelihood of a false negative goes down more and more. So if you want to wait a couple more days, it's probably not necessary, but should help ease your mind.
