Please, please try to remember in the infertility world, everything is relative. There will be many people on this forum who would be ecstatic to have 7 eggs collected.
I know it is difficult when you may have been hoping for more eggs, but please try to see 7 as still a good number of eggs collected. I would have been very happy with 7 eggs (early 30s, normal AMH, no health issues, but for some reason always a poor responder to stims).
Progression rates from egg collection to day 5 embryos are all averages, and your eggs could do better than average.
My first egg collection was a disaster - found out I was a poor responder despite on paper having no fertility issue (doing IVF due to needing donor sperm). We only got 4 eggs, 2 mature. Both made it to Day 5. Had a BFN fresh transfer and CP.
Second egg collection was ecstatic to get 6 eggs, all mature. All made it to day 5 but only 3 were suitable to freeze. First FET is my DD and I'm 40 weeks pregnant from second FET.
Even with 'lower' number of eggs, you still have a good chance of success. Hope this gives you some hope and perspective. Wishing you best of luck over the next few days, as day 3 and day 5 updates were always the thing I found the hardest about the whole process
