Aww, Shannon my heart just ached when I read your post. I was also 8wks but I did have a D & C because my body didn't realize it was not viable (a missed m/c). I also took HPT's at home and mine came up positive a solid 2weeks after (and usually with a D&C your HCG drops faster). Finally at 2weeks and 4 days it was negative.
Like you said, it was hard to look at those positive tests.
I feel for you. For me it did feel better (odd as it may sound) once I saw a negative test. It meant I was one step closer to TTC again. But nothing will replace the sorrow for your Angel. T&P.
