I'm pretty sure that around about now I should be benefiting from "happy hormones", and that this affect should last until soon after childbirth. But I haven't noticed any increase in cheeriness or laid-backness, which is unfortunate because I've never been that laid-back to start with and sure could do with some. My moods are, on the whole, about the same as always; I'm impatient, easily annoyed but can't hold a grudge, and am most grouchy when I'm stuck in a hot car or cruising the supermarkets with my mother.
On the other hand, I have noticed an increase in weepiness. Only yesterday I was watching Bargaining I and II from Season Six of Buffy - they're the episodes where Buffy's friends bring her back to life, not realising that they've taken her from Heaven. I wept like there was going to be a tear shortage or something.
It was worst in that scene where Dawn finds her newly-revived sister (who has just clawed her way out of her own grave) on top of the tower thing which evil shoe-loving goddess, Glory, built in the previous series - the place where Buffy sacrificed herself to save the world. Dawn's fear of losing her sister again and Buffy's returning memory of her last moments on Earth - ah, it was Tear City, Arizona.
If you know the episodes I'm talking about, then you might agree that they are pretty emotionally heavy scenes, which could make you cry even without a dose of pregnancy hormones. Okay - I also cried during Once More with Feeling, the musical episode.
