day 3 embryos

hi, just started our first round of ivf.

just had my retrieval about 3 weeks ago, and I cant stop thinking about our results.

I have pcos so my dr did advise me that we would have a high number of eggs but most likely not mature enough. so we had 38 retrieved, 15 mature, 9 that were frozen on day 3, and 6 that didn't make it to blast.

we have 9 frozen embryos, im not sure what "grade" these embryos are, but was told they are being transferred by 3's. so technically we have 3 opportunities to do a fet.

I'm stressed, and overthinking that none of them made it to day 5. and just want some insight on how many people actually had success with day 3 embryos. I've done my research, but just want to hear from actual people.

we have been ttc for 9.5 years and I was so hopeful starting ivf but I can't help but feel like I took one step forward and 2 steps back with these results 😭
