Thank you all for your thoughtful replies.

It's is still killing me, I had a burst of energy today so did alot of cleaning and reorganising furniture in the kids room. And now I'm paying big time. I really think that I just might be over doing it. Going to try and rest up tomorrow, no walks or cleaning and see if it improves over the next day or two, if not I think I might go to the chiro and see what they think.

Thanks Julie for the info sheet. It's funny reading through would are possible symptoms of SPD and OMG I think I have been suffering nearly all of them. It's easy to just put it down to 'normal pregnancy aches and pains' but after reading the article I can see how I can be doing things to help prevent them or to make them better. I think a visit to the chiro is definately in order if I don't improve soon, I'd hate to do myself some serious damage.

Thanks again ladies.
