Why Testing Early Can Suck - June 30 - July 2

I could not help myself and started testing early. That is very easy to do when you can get a package of dip strip tests online at about $10 for 40 tests. I tested on Wednesday night - 8 days past IUI (DPIUI) and got a very faint positive result. I was over the moon - I couldn't believe it had worked on the first try! Holy schmoly! But as it was so very faint, I decided not to post anything until the next day when I could confirm that it was getting darker. So, I tested again Thursday night and didn't think I saw a line at all. =( I wasn't sure if it was real or just a fluke, so I waited until this morning (Saturday) to test again, figuring I would get a much darker second line if there was one to be had. Alas, there was not. I am 12DPIUI today, and not even a hint of a second line. I am fairly certain I am out this cycle at this point. I didn't think we'd be lucky enough for it to work with the numbers we had this cycle, but I must admit that with the strong progesterone number and that faint second line, for a day I was convinced that it had. Back to square 1 - AF should arrive within a couple of days.
