8 hours of agony

My U/S is in just over 8 hours. 8 long hours. To make it that much worse, I had an 'issue' this morning.
I got up around 4 for my second nightly pee break. Nothing unusual about that. I peed, the normal amount. So far so good. I wiped - blood. I grabbed some more tp and wiped again, more blood. Lots and lots and lots of pink blood. Needless to say, going back to sleep wasn't an option.
I've spent the last couple of hours surfing, finding success stories and stories of doom and gloom. I don't know what is going on.
I've since been hitting the bathroom every half hour or so, just to check. The first followup was mostly darker leftover looking stuff. But since 5 there has been nothing.
Of course I'm concerned. As planned, in anticipation of a good u/s, I told my C level and HR VP yesterday. Was I being too optimistic. I don't really believe in jinxing, but was I wrong to be happy for a while?
Anyway, time will tell. My scan is in just over 8 hours. It could be bad news, it could be good news or it could be one of those horrible "we're not sure" trips. Sigh.
I'll post an update after my scan or if I start to bleed again.
