I figured two of the three can be of some comedic value.
If she's hiding out with a bunch of teens. The oops I peed myself embarrassment could play well. I think the peed myself thing could play even if she's all alone. Even if she quickly realizes what it really signifies.
Then the whole cleaning frenzy. Imagine a bunch of kids watching helplessly as the nine month pregnant woman starts cleaning everything, blaming them for not helping her and then pushing them out of the way 'because they're doing it wrong' once they've been brow beaten into helping.
All they can do is stand by helplessly and protest she's going to hurt herself or the baby. (this nesting suggestion sticks close to my actual experience with the first one, only no teens involved hehehe)
