Which tarot cards? I’ve seen a lot, and I’ve only seen one that mentions that.
I don’t think that’s worth worrying about though. I have a feeling that she wants people to think she conceived as soon as possible, but I suspect she’s going to have a harder time conceiving than most people think. This summer just isn’t a good time for those two to be attempting conception.
I mean, look how slight she looks in this picture and remember that the camera “adds ten pounds.”

Also, boobs get bigger when you’re pregnant, and there doesn’t seem to be a big change in her upper torso. Just slouchy posture.
