OKay, even though I dont have any kids, that has got to be one of my worst fears so I did a little reading on it. And, I think I am almost as afraid on an enema as I am of pooping on the table. I read in several baby books that you can get gylcerine suppisitories (they are completely safe during pregnancy), and when you know you are in labor at home, just insert one and you should have a BM in about 10 minutes. That is what I plan on doing because I would just die of embarassment if DH saw me go poo, baby or not
Anyway, I hope I have helped calm you down a bit, I don't blame you for being afarid of that!!
