I just did my third fresh IVF cycle, transferring 3 embryos of very good quality, one has started compaction on day 3.

I never achieved pregnancy with the previous 2 fresh cycles and FET. I changed to another clinic and was treated with IVIG for elevated NK activity.

I wonder with 3 good quality embryos, what would the chances of having a triplet? I read from some other postings that statistically about half of the embryos at day 3 do not make it to a blastocyst. Is that correct even for good quality embryos at day 3?

Treating the elevated NK cell activity will improve your chances of a successful and sustained implantation.

The 50% drop out rate is observed accross the board for all embryos, and does not apply to the "good" ones. Embryos that have reached the 8-cell stage and exhibit little or no fragmentation on Day 3 (i.e. the "good" ones) are more likely to continue to the blastocyst stage. Compaction is also a good sign. Each 8-cell embryo transferred has about a 20% chance of implanting.
