So I'm just so confused. My LMP was 6 weeks ago, had early scan as had tiny drop of dark blood when I wiped. Went in for blood test and it was 7100, was sent for u/s next day. Spotting stopped completely. Sac only measured 4 weeks 5 days??? How could this be as I chart my temps and i don't thunk it makes sense?? Has anyone ended up having the same thing? What was the result? Really appreciate anything!
