Everything crossed for you Quod...
Mega ouch Cavort! Were they definitely BH or could they have been stretchy dehydration cramps (ie like a calf cramp, but in uterus)? I keep getting these when I don't drink enough water and they hurt loads.
Had an interesting night with approximately 90 minutes of sleep - due to a combination of horrendous heartburn (had three top-ups of gaviscon), and being completely wide awake as a result of the news that our four-weeks ahead of us pregnant friends are no longer pregnant - they had their son this week - four weeks early!! 
They're all ok apparently (no details yet), he's 5lb something and fine, but I can't get it out of my head that 'hold the phone, babies come early!!!' and swaying between hope they're ok and it wasn't too stressful to omfg what if my waters go at my desk.
Huuuge reality check!
Don't know about them but I think I'm a little in shock!
Also had a hilarious trip round Tesco last night whereby I was struck by cramp in my toes so badly I had to keep stopping. Was really quite painful but all I could do was laugh each time I ended up stock still in the middle of the aisle, bent forward with my knee bent, trying to prise the toes back into place.
Must. Drink. More. Water. Today.
