I feel like a moron saying this, but I think I may be going into labour. It's been different every time, so I honestly am not 100% sure, but I'll be willing to call it 90 - 95% sure. There's an awful lot of "holy shit that hurts" cramping stuff going on, although nothing resembling a regular pattern of it, and (TMI Alert) a lot of mucusy discharge.
So. I'll update if I can. If not, well, I'll update when I get home.
