HCH at 25 after 9 days of transfer! Please help!

HI!

I did my 5 IVF 2 weeks ago ( 08/02 ) and last monday ( 08/11 )  I had my first HCG test (  9 days after transfer) . It came at 26. Did again yesterday and it came at 85, but they said to be cautious optimist. It could be another chemical pregnancy or a late implantation.

I had 42 eggs retrieved and 28 was mature, 12 fertilize, we  lost all of them but 2 that we transfer. One of them was an early blast and another one was 24 hours late.
We wore not optimist at all, because the same thing happen last time and I Had a chemical pregnancy.
I had same spotting around last saturday and sunday and also some spotting on Wednesday.
Does anyone went thru the same thing? What are the numbers for the HCG for this early?
Any hope?
Thanks
