Day 3 transfer w ICSI

Has anyone had a BFP with a day 3 transfer and ICSI? I am currently in a second round of IVF and due to sperm morphology, we had to use ICSI for the fertilization both rounds. During the first round, we had a day 3 transfer. With this second round, we (incuding my RE) were hoping for a day 5 transfer so we could study the embryos more before the transfer. Then, I just got a call saying that they are targeting for a day 3 transfer. I read in the web that day 3 transfer's success rate is very low, especially if you had ICSI. In fact, if the embies that they transferred in day 3 were left alone in the lab to day 5, they probably would not survive. I just feel so hopeless and I feel like that the RE just want to get the embies into me before they all die on day 5 in the lab. I need some hopeful stories.
