[QUOTE=Francesca13]Your numbers (and confusion!) sound very similar to my IVF cycle!
We had 10 eggs retrieved. All 10 fertilized, but two of them did so a bit late. At day 3, all of them were still growing…but I think 6 of the 10 were right where they want to see them. Then, at day 5, I had a 4AB and 1 “early blast” which would’ve been a 1 or 2, but my clinic doesn’t grade them until they are a 3. We ONLY transfered the 4AB and are currently 13 weeks along with that one. The early blast grew to a 4CC on day 6, which they did not freeze due to not meeting criteria. I think 3 of the other ones were also still growing at day 6…somewhere around a stage 1 or 2, but my clinic only freezes 3BBs or higher.
So, of 10 eggs retrieved and fertilized, only ONE was really “good”. I had the same question as you afterwards. Is something wrong with my eggs? We used my DH’s sperm, and I also read what you did about a big dropoff between day 3 and day 5 being a “guy problem.” My clinic, however, said our response is very normal. They were HAPPY that we only had one good follicle because the true cream of the crop really did expose itself.
And, here’s the main point of this post: I really do believe that a few of those other eggs I had would’ve made wonderful babies, as well. They just didn’t respond as well to life in a petri dish, or didn’t measure up to my clinic’s standards for freezing. Making them grow for 6 days outside the womb doesn’t work for all eggs…I’m guessing if they had been transferred as 3-day embryos, we would’ve had a chance with them. But, they can’t tell as much at day 3, so it makes sense to wait until day 5 to really find the champion. But, your response was sooo similar to mine, and a lot of other women I read about on here. I don’t think there’s anything wrong with your eggs…the blasts you got were good, and just didn’t take.
I had some of the same thoughts - that maybe some of the embryos that they discarded could have made it. Makes me sad to think about.
