You might be pregnant if ...

Recently one of my friends pondered how one knows when one is pregnant. My friend had heard of my salty, starchy, creamy food cravings (like for mac & cheese, pictured) and was concerned about sharing the same cravings. In the friend's case, I think the pregnancy quip was a joke, since this friend is a man. But this got me to thinking: what are some good non-scientific tests for pregnancy? Ask yourself the following questions -- if your answer "yes" to several of them, you too may be pregnant.

• Are you constantly thirsty?
• Not coincidentally, do you wake up to pee at least 2x each night?
• Despite your water chugging, do you have lizard-like dry skin?
  
• After 4 a.m. bathroom breaks, is it impossible to fall back asleep because you're obsessing over minutiae (like which papers you've graded and which ones you still need to grade?)
• Does the sight of normally minor household annoyances (like a couple ants, or unwashed dishes) make you cry uncontrollably and feel like the household is spinning out of control?
• Do you need to eat constantly, yet feel like you could puke at any moment, for any reason?
• Do you order things at restaurants that sound delicious when you look at the menu, then seem repulsive and inedible by the time they arrive 10 minutes later ?
• Has your cup size increased exponentially? (Results may vary for male and female respondents, and the "cup" in question.)

There's also the sex thing, but that's a scientific test.

Am I missing anything?
