I'm newly pregnant (5w1d) and I just started a new job. I was told by my recruiter it was business casual, but the other people on my team were wearing jeans today. I would much prefer to be wearing jeans at least occasionally because my last job was pretty informal.

The problem is that I don't have any jeans I feel would be work appropriate. But I'm not sure if I should buy maternity jeans or regular ones. Regular ones are going to have a pretty short life span, but I'm not sure I"ll fit into maternity ones yet. And another important consideration - for now I'm keeping the pregnancy under wraps so jeans that are obviously maternity would not be a good idea.

Which would you buy?
