HCG Numbers - IVF Pregnancy

We did an IVF Cycle combined with PGD (Array CGH Test). Egg Retrieval was on 3/15. 22 Eggs retrieved, 11 fertilized and PGD biopsy done on those 11. 8 came back normal, 2 had chromosomal issues and 1 could not be tested. 4 Embryos were transferred on 03/20. Pregnancy Test was on 03/31. Came back positive but very low HCG numbers. Below is the HCG Progression:

1) 03/31/10 HCG 10.9
2) 04/02/10 HCG 26.7
3) 04/04/10 HCG 86

Doctor's office are telling that it does not look good for this time post retrieval / transfer but the numbers are doubling (from 1st to 2nd) and tripling (from 2nd to 3rd) every 48 hours. So, am absolutely tensed on what is going on. Have had a long journey trying to have a baby. Anyone had a successful pregnancy with low initial HCG numbers? Please help.
The Doctor's office is telling me that the numbers are too low

Hi!
I HOPE things go well.  I guess I must agree that the prognosis is "guarded".  The numbers look beautiful except they are so low.  Hope and Pray and take good care of yourself and if the numbers continue to increase, eventually you will have a baby.
If things don't work out this time you must have a few frozen embryos too?
Your ovaries are champions, so don't give up!
Good luck!

Thanks for giving me hope. We do not have any frozen embryos. The Embryologist said that none of them could be frozen.

I had another HCG test today and the numbers are going up. It is upto 236 now, which is almost thrice as the last HCG test (86).

The doctor has asked me to come in for an ultrasound on the 12th April. Is that kind of early to see anything? Am I out of the woods or do I need to keep my fingers crossed until the 12th?

I had several Beta HCG and U/S scans since. My HCG numbers are still going up and are now at 7280 but they are raising slow as in the beginning. They are now taking anywhere from 3 to 4 days to double. Doctor says he is cautiously optimistic now. The most recent U/S showed a gestational sac of 8 mm, a Yolk Sac and a Fetal Pole with a CRL of 2 mm. Heart beat could not be seen or heard. I have been asked to go for another U/S next Tuesday (Apr 27). The Doctors think I am about a week late. Is this possible in an IVF PGD Cycle? Are PGDed embryos slower to start with?
