Addicted...to peeing on a stick

Ok, I must admit.... I think I am addicted to peeing on a stick.  I have taken pregnancy tests since the day before the babies were even transferred to me.  Why? Well, the reason I did the day before was just to make sure it would show negative and that due to medications/hormones they have me on would not cause a false positive result.  Indeed it was negative.  This tells me that the first sign I see of a second line indicating a positive result would be an official positive!

There was an 8 day wait between the transfer and the day I had to go back for bloodwork to determine if HcG levels were present, indicating that I was pregnant.  I am impatient and could not wait 8 days.  Heres a picture of the huge stash of tests I have taken of the past 7 days.  I know, it's a bit obsessive :)  Sometime I would take 3 tests a day, morning...noon...and night just to watch the line to see if anything changed.  Sure enough, on August 7th, 4 days after the transfer, the positive line began to show very faintly.  When I say faintly...I mean that I had to tilt my head, quint my eyes, hold it at a certain angle with proper lighting to be able to see it.  At this point I am thinking that maybe my eyes are playing tricks on me and that maybe I am only seeing what I WANT to see.  But the days following would prove the test to be correct.  The lines continued to get darker :)

                                              Tests taken between August 2nd- August 10th
                             All tests on the left are negative, and the tests on the right are all positive
