I can't relate specifically, but I had a bleed at 5 weeks, with which I spotted for two weeks. I went in a couple days after the big red bleed and the doc saw one healthy embryo and heartbeat and what they told me was a second (possibly empty) sac. Then 3 weeks later, I came back and the "sac-like thing" was gone completely. The other doctor told me it was probably a clot. But, at 8w5d, I had one little bean with a great heart beat, arm buds and all.
So, if it was a clot that that was bleeding out, I can relate this to you as positive. It was a large bleed with clots and everything. I thought for sure it was over. So, you can still bleed (quite a bit) and everything be okay. My baby (and many others) have made it through bleeding episodes! My sister also bled in her pregnancy and she just found out today she is having a baby boy!
Sending good vibes your way! I know this isn't your exact scenario, but I hope it helps ease your worries a little until you know more.
