"Is more likely to become .. " or "more commonly becomes" would make more sense. Nonetheless, what you are getting at (treating individuals as members of a group) is precisely the problem. Treat people as individuals, even if you believe expecting mothers to be a bad investment, don't assume every woman is more likely to become pregnant.
If not that, what exactly are you saying?
I am speaking very clearly. Pregnancies are common and normal, plain and simple. Use whatever word you like. Regular, normal, usual, routine, etc.
> I have no idea where you're getting that idea
from here:
> if I had to choose one group where problems would be more likely, I would choose the group that routinely becomes pregnant and raises children
I'm in good company:
Only a 3rd grader thinks its ok to trot out their thesaurus and willy nilly replace words.
(also, from reading this thread, I don't seem to be the only one who thinks your english leaves something to be desired)
