Another loss :(

I had convinced myself that all of those hpt lines on the Accuclears were evaps, even though they were much darker than the prior evaps I had seen on that brand. I know differently now because I passed membranes last night. I showed them to DH and he agreed. It was a triangle of tissue about 2 inches by 1.5 inches, with on corner more magenta colored and more cream colored on the other side. Typical membranes. The one part that has me baffled is that my beta was negative. I know it was a very weak pregnancy, but the beta should have shown somewhere between 4 and 5, with the kind of hpt lines I had been getting. But whatever. It was another pg that was going nowhere. What else is new, right?
