If a pregnant woman gets up to pee she'll realize she has to blow her nose.

Once she blows her nose, she'll realize she can smell again and that she is possibly hungry.

Once she realizes she's hungry, she realizes she has to throw up first.

Once she throws up, she realizes she needs to get some saltines and lay on the couch for awhile.

Since she's laying on the couch, she may as well open up the laptop.

Once she opens up the laptop, she'll feel like blogging.

Once she blogs for awhile, she'll realize she has to pee again...
