Can I get opinions?

I had my egg retrieval last week, two days before my 41st birthday. I got 33 eggs, 25 were mature, 21 fertilized and 5 made it to blast. 3 day 6 and two day 7. Doctor said all 5 were solid B quality and had a 70% chance of implanting if they came back from the PSG testing normal. I guess I’m just worried that more didn’t make it to blast. Do you think the means I have less of a chance to have the PSG testing go badly?
