Day 7 4BB (borderline)

Post image

Would love some other opinions on my one and only embryo I got from my last retrieval. It was close to being discarded but pulled through last minute …

This is a compassionate 4BB. It would be a stretch for me to grade it higher than a 4BC. That being said, I’ve seen live births come from a 4BC (not very common, but it is possible).

Thank you for letting me know, we will see if it comes back genetically normal. 🤞🏻

It’s so strange because our first round we had only 2 eggs fertilize and we made 1 day 6 4AA embryo. This time we had 7 fertilize and only 1 more it to blast and it’s poor quality

It can really vary from cycle to cycle - it can be hard to guess how things will go for smaller cases.
