31 weeks here. One word for the week: heartburn. I've just bought packets and packets of Rennies.
For what it's worth, I tried to read the hypobirthing book for first baby. It reminded me of the Hobbit: incredibly tedious and was only going to be finished if I turned several pages at a time. (I didn't go to any classes as I've always been the one to be thrown out of yoga classes for laughing).
The only thing I took from the book, is how to slow your breathing: your 'out breath' should be twice the length of your 'in breath'.
Labour hurt, of course it did, but concentrating on breathing (ie the counting as above), and taking yourself mentally away (I pictured every detail of the pool at a hotel from our honeymoon-temp of water, temp of air, smells in the air, what I could hear, what I could see, literally every minute detail), gave me control.
The whole labour thing is so overwhelming on every front, it is easy to sink into panic. I found I could keep away from the precipice of panic by breathing and concentrating. It's also worth remembering that you only need to concentrate through each contraction-you can rest in between them.
Anyway, I just offer the above in case it is of any use.
