I think I might be pregnant!

It's been four days now since I should have seen a period, I was due on Monday. Maybe, if that is the case, I am pregnant. That was the reason last time I was late, some 20 years ago?

The trouble is, I can't remember some handsome hunk taking me in his arms and wooing me to the point of making a baby. Nor can I remember a flash of light followed by Archangel Gabriel declaring that I am with child at my window.

But what else could it be?
