Hi ladies, it's your favorite worrywart here 
, and I'm calling on your collective wisdom once again...
So my transfer was this morning. I transferred one high-quality hatching blast. For that, I'm grateful and hopeful and excited and nervous. Burrow baby burrow!
But the rest of the viable embryos were at the morula stage today. There were 18 of them. So, we transferred the one and only blast of the whole bunch. It just so happened to be of very good quality.
Even through my Valium haze, I felt shocked when the doctor came in and informed us that we had only one blast on day 5! We had such an excellent retrieval, fertilization, and 3-day report: 34 eggs, 32 mature, 29 fertilized, 22 dividing normally on day 3. I thought for sure we'd have a handful of high-quality blasts from which to choose today, but we didn't. I'm keeping my fingers crossed that this one little guy - the speedy one of the lot! - is our THB.
The 18 morulae are going to stay in the incubator for another day. Hopefully some of them will make it to blast. The ones that do, we'll biopsy for PGS testing, and freeze. I'll get a call from from the embryologist tomorrow.
Does anyone have experience with slow-to-develop embryos? Does this mean anything in terms of quality? Is it normal for a batch of embryos to take 6 days to reach blastocyst? I'm just feeling kind of worried about this.
Thanks for any thoughts...
Annie
