I have to say, it's a bit of a relief to know I'm not the only one with weird aches and pains, I'm sure the other pregnancies didn't affect me this badly.
Just a note - the lower back pain comes from your centre of gravity shifting forward, your back muscles work overtime to compensate for the shift and if your core muscles aren't in good shape you'll experience a fair bit of pain as your musculature tries to compensate for the change in balance.
