Just so you know, I birthed Emily standing up, and Nina on my back, I had hemmeroids for about 3 months after having Emily, but only once after having Nina. And with both girls, I only pushed for about 5 minutes.

Hopefully you're one of the lucky ones that just doesn't get it.
Good luck with your impending birth!
Sorry Jodi. That really sucks.
My advice didn't come from a place of experience (given that I was indeed a lucky one) but only that I've been told that not straining is a preventative tool for avoiding them (in the context of going to the toilet). We all know that you have to push to get a baby out, particularly a first baby because your uterus isn't as 'experienced', so the thinking here was by using gravity rather than pushing hell for leather when your body isn't telling you to, would be another preventative tool, I would've thought.
Obviously for some (like yourself) it sounds like it is unfortunately unavoidable.
I hope my post didn't offend anyone who got them even though they "prepared" extremely well for their birth/s.
