Really sorry for you Beau, I hope it is not a miscarriage but the waiting to know for sure is agonizing. It's not quite the same but I had bleeding like this at about 5.5 weeks with my last pregnacy. Didn't last longer than a day and can't remember cramping in partciular but I was convinced the first time I saw blood that it was a miscarriage. Because it was so early I had a couple of options, do the bloodwork or wait til 7/8 weeks and see if a pelvic ultrasound could pick up a heartbeat. I decided to wait for the ultrasound since the blood test wouldn't give me immediate results either and I just monitored the bloodloss at the time. At my ultrasound the tech found one healthy 8 week old and one empty sac. She explained that situations like this (think it's called a blighted ovum) are surprisingly common and that we only have found out how common as ultrasounds have improved in quality in the last decade. In my case it was comforting to know that the bleeding could be explained and that it wasn't likely to happen again. It is still possible that things are ok. Hope you have support during this time.
