My first pregnancy was a lot easier than this, too.
For a start I didn't have SPD, only had a textbook amount of MS in fact the whole thing was textbook, is it possible to be jealous of yourself? whereas with this one it was horrendous, and the lack of energy is ridiculous!
Also got a bigger bump than last time, and my previous stretch marks are beginning to turn red again :( Sob, sob...
Not to mention the bloody crazy dreams this time!
I'm sorry to hear about everyone elses bruises and ailments, the things we go through for our children eh?! 
DH Definitely sounds like an iron deficiency to me. I was feeling exactly the same, so I went and got plenty of iron rich food, tried to get some iron supplements too but the pharmacy told me to talk to my doctor first as they vary in strength.
So i've just been eating a lot of iron rich foods and a lot of orange juice to help absorb the iron, and now a few days later feel a lot better. Not 100%, but can now stay up all day without a nap 
I've got a physio appointment today, it's my first one. Does anybody know what they actually do at the first appointment? Will they just tell me to go home and bounce on a ball?
