How is a baby like a suitcase?

I'm not usually superstitious, but I bought pads today.

How is this superstitious? Well, to backtrack a little: when we went on our honeymoon, our luggage went missing. It didn't turn up the first evening, and it wasn't there the following morning. We were starting to get anxious (as well as feeling grim from wearing the same clothes and not brushing our teeth two days running), and finally we said, "You know what? If we start buying replacement supplies, our luggage will definitely turn up." And so it happened: we went to the chemist, bought new toothbrushes and deodorant and sunblock, and returned to the hotel to find our suitcases waiting for us. I've had airlines lose my luggage many times, and this technique always works: buy some replacement stuff, and your cases will magically return to you.

So I was at the supermarket this afternoon, and when I was going through the pharmacy aisle, I thought, "Hm, am I going to need pads this month? If I don't buy them, I'm definitely going to get my period. If I do buy them, luggage logic predicts that they'll sit unused in the bathroom cupboard for nine months." Worth a try, right? ;)
 
(If it doesn't work this time, I'm going to fork out €30 for a Mooncup next month. That should get me knocked up with twins.)
