Ultrasound number 4 : Little Embryo , Where are you ????

Last week on Monday I had my ultrasound number 3 , and I was devastated with the results , embryo suppose to be 7 or 8  weeks , but is almost invisible in the ultrasound  , the radiology Technician and I we only could see a little point  hidden in a corner  with a clear  heartbeat of 59 bpm , she say  the embryo looks like  5 weeks and 4 days .
4 weeks ago  I had an ultrasound and it shows a  6 week  2 days baby with signs of  bradycardia  ( only 47 bpm  )
Today Monday 2 of december  Scan number 4 :  I got the  worse radiologist technician I ever had , very arrogant and stink  cigarette oddor. It was disgusting  but I had to do it , I was needing some answers  or some relief  after last  week .
So first  I ask if it was possible to have a female  conducting the ultrasound ,( but there was none) , as I have a retroverted uterus that in many cases don’t let see anything  in the scans so we always finish doing  vaginal scans  .
The initial ultrasound of my womb  shows  the sac , but he actually though I was too early . When I explained  that I already had 3 previous scans,  he look at me  as If I am crazy , when I try to explain that we saw the heartbeat  and the little embryo 3 weeks ago .
He say something  like ” is very clear  there is nothing here ”  so I beg him to please  perform a vaginal  scan  as I would prefer it .
although  the technician was very uncooperative, he was very unkind and  even unprofessional , he still perform the Vaginal Scan ,  I guess because my hubby was there trying to support me , and gave him  the look .
Although the radiologist  didn’t mention  anything during or after the scan , Brad and I we could  see it , It looks like a  blighted ovum , I know blighted ovums , from my last  2 pregnancies , the difference  today it was that I am  sure that 1 week ago  there was still  a little embryo  with his heartbeat  and fetal pole there  and  3 weeks before that scan , I  could perfectly see  the little embryo with his heartbeat .
so what happen today ?
where is my little baby ??
I am totally  devastated ,  I can not think , I can not  function . I was thinking something was wrong , but  today  is totally  worse ,  my little  embryo has vanished from  the sac ……    what a day  :-(
