My 8 week old DS hasn't pooed since Tuesday. Is that ok?

Other than that, he doesn't look uncomfortable or in pain, except times when he has wind.
Still, I'm worried that it may not be good for him.

Not a problem....many babies go a few days bewteen dirty nappies.....he'll make up for it

Plenty of wet nappies I assume and feeding ok?

You could try bicycling his legs at nappy changes.

Yes, plenty of wet nappies and feeding is fine.
I've done the bicycling (or more like lifting his knees to his chest) thingy. Maybe will do more.
I'm gearing up for an explosive one that knows no boundaries. While waiting, it's assuring to know it isn't a worrying issue.
Thanks!
