Had my duck eggs upside down in incubation

[Ahygre21]

This is day 18 of incubating my Pekin ducks eggs. I was doing some reading and it said that the air cell should be at the top. Well, I just realized half of mine were the wrong way. I did pointy end down, but didn’t pay any attention to the air cell. Did I wreck my batch? Is it too late to flip them the correct way and hope for success?

The eggs should be pointy end down. Do you have pictures?

I can take some pictures. Pointy end is down, but it seems air cell is on the bottom too
