Hey Panda,
Don't know if this will make you feel any better but i can certainly sympathise with your situation.
I was supposed to get my kitchen completely refurbed (units, plumbing, floor, new french doors, new back door, replastered, tiled and painted) in August. I arranged care for my dog. The day before the builder had to delay the job - major problems with a previous job, too late for me to cancel care for the dog and i couldn't afford to pay twice.
They eventually started in mid September when i was 30 weeks - it took 2 weeks and I had to keep coming home from work to take my stressed dog out on a regular basis grrr.
It was unbelievably stressful and i spent most of the two weeks crying! But when it was done - my goodness the relief and now 2 weeks to due date and i'm so happy with my fully functioning beautiful kitchen, it was worth it.
My bump moving around is probably the one thing that got me through, knowing the reason I was going through the stress was so i didn't have to put me and baby through it when she arrives.
For indigestion - send DP to the 24 hour Tesco to get you some gaviscon.
I know it's hard but try to relax - listen to some gentle music in the dark or try some deep breathing (although in honesty my baby loves it when i do deep breaathing and tends to move around more lol).
