Addicted to Home Pregnancy Tests and negative, negative, negative....

The crazed HPT addict has struck again. After my last post two days ago, I took a First Response HPT, and guess what, there was a very faint line. Wooo Hooo I thought...we did it again, this is AMAZING. We kept checking the two tests I had taken to make sure that there were really lines there...and although they were much much fainter than the ones I saw last month, they were there. Well, after and hour the one on the First Response disappeared completely. I have never had that happen before. I know that I do not have hCG left in my body as I had Betas performed until my level went down to 0. So I took another CVS test the next morning (yesterday) and again got a very very faint 1/2 line. Paul went out immediately and bought more tests...a Confirm and another pack of CVS tests. I took a Confirm that afternoon and it was negative (even after 4 hours). We must have stared at that thing for 3 hours combined time in every light imaginable *trying* to find a hint of a line...and there was nothing.  Then I went on and took another First Response (crazed, am I not) and this one was totally negative. (of course it was) This morning at 10 DPO, my temp dropped to coverline...so I knew nothing good would come of testing today. So what did I do???? I took yet another CVS (uping the anti of HPT's for the weekend to about $60) and it was negative...not even a faint little 1/2 line. I am not pregnant and we are now broke. I will just wait out the last 5 days of my cycle now (AF is due in 5 days) and then I can start Clomid. *sigh* Now I see why everyone says not to test early...
