December 3 2013 : Vanished embryo ? or retained miscarriage ?

I have been sitting in my room trying to find answers ,  If you have ever live a miscarriage , you have an Idea of how it feels  like .

• What happen with my little baby ?  how is possible for an embryo to vanish/ to disappear and become  a blighted ovum within a week ?
• What will happen next ? am I going to allow the doctors to preform  a 5th  D&C ?  would it be possible to have a “medical abortion” instead ?
• On monday I have contacted Dr Professor  Gavin Sacks in Sydney  with the hope he could help me to save this pregnancy .But the pregnancy is lost already . Should I still going and see him  as  it will be very expensive  and possible nothing we can do right now .

I haven  sitting around  just thinking in all the things that happen last week after monday I was in my ultrasound appointment .
I was very very upset , I think I cry a lot  that day and that night .
Next day I was little bit more upset ,and  at night and when Brad touched me he  told me I had little bit of  high temperature , so he put  some cold  compress on my body to lower my temperature , the whole week I had  night sweats and  one of the  days I complaining  of sore throat  , I also went to the doctor  because I was having Cystitis , so he send me a course of antibiotics .
on thursday I went to a doctors appointment and I ask for blood tests to see my progesterone levels and my hcg leves .
On friday , I went to visit my friend Mia  who is  pregnant ,   we  had  some homemade smoothies  and a muffin :-)  it was actually a good day .  When I came back home  I went to  Pee and then I notice  a  thick red line in my undies . I called Brad , He said , Is better this way ,  you are having a natural miscarriage , just let it  happen .  :-(  we  hug ,  I cry .. ..  I was prepared for having a natural miscarrige , I went to sleep , and next day  , there was nothing in my  undies , so I assume It was probably  little bit of spotting , I blame  the fact I the day before I took my drugs  little bit late  ( I’m talking about the prednisone  and the aspirine )  That saturday , I actually felt  very good , I felt  little bit pregnant again , and my boobs were sore again  ( my boobs stopped  being sore about a week  before  but as I am taking prednisolone and  clexane  I though may be  my pregnancy  symptoms were hidden  because of the drug ,  on saturday I started some vitamin B6 and B12   , and I just felt my energy  was back .
Sunday , I got my  Hcg  levels and Progesterone levels  results , I was not totally happy , but I actually felt more relax  my progesterone levels went up  , not  too much , but double from  7.7  to 15.55 nmol/l   in   about 3 weeks , still  very low  considering  the healthy progesterone levels  during pregnancy start at 39 nmol/L ,  my HCG levels  Increase , but   not double or even triple in this 3 weeks , but they increase and I  was still within normal levels . My Hcg  Actually  shows  little bit of my past pregnancy in 2012  in which  my levels didnt past the 1400′s  range .
I really though this pregnancy  was gonna be the one .  Actually I always kept the ilussion  that every pregnancy was gonna be the one .
