Wat is my baby telling me?

I recently got a positive test result at my doctors!! Im very excited! I had some brownish red bleeding for a couple days and she sent me to my OBGYN- He gave me a Trans l ultra-sound but there was no embryo? So later that day i got blood work done to to see my HCG levels then 2 days later i had my blood HCG taken again. That day i went to the ER because of gall stones (gall bladder disease) and i actually started to bleed a bit dark reddish blood kind of thick.. not heavy though (and yes ive been monitoring with a pad) some very tiny almost un recognizable blood clots too. but no cramping. So he took a look and said that it was a threaten miscarriage (and ive had one b4 but it was much quicker found out one day next it was gone) So the next day i got another trans l done to rule out tubular or ectopic.. and once again nothing appeared. Im starting to get nervous but on the good side he told me my hormone levels are high and rising :) but im so confused on what to think. he also said if it was a miscarriage he's see it by now. so he thinks its either too early or a belightned ovum? ugg.., i dont know. now i have to wait 3 days to see wats going on.. and my bleeding has seemed to be reducing
