Q&A: How do you know when you're about to have a baby?

I thought this one was too silly, but then realized it might be kind of interesting. I was asked by a random pregnant stranger on public transportation how you know when you're going to have the baby soon.

The obvious answer is "when contractions start," but she was looking for the signs before that. She was within a week of her due date, so it could happen anytime.

I was thinking about it, and came up with the following:

* bloody show or releasing the mucus plug

* manic energy

* nesting/cleaning

But I couldn't really come up with anything else myself. Are there other things that you have experienced (or that you've heard) are signs that you're going to go into labor within the next few days?

With me personally, I lost all fear of labor because I was just so done with the whole process. I don't know if that's common, though.

I'd be interested to see if this is something that's common across cultures, or if it's got some cultural specificity.

So. What would you say if someone asked you if there's any way to know? Conversely, are there signs that you're *not* going to go into labor any time soon?
