After a week of steadily increasing pain when I moved I went to the doctor yesterday and found out I have SPD.
I now have painkillers and a physio appointment in 3 weeks but despite looking on the Internet I can't find much advice on what to do for the bast in the meantime.
If you have been through this was gentle exercise/walking recommended or were you advised not to move any more than necessary and to avoide the things that are causing pain - which includes walking for me 
Also the pain is particularly bad after I have been sitting in my chair at work, I don't know whether a cushion on the chair would help, I don't want to do anything in case it makes it worse.
I was relaxed about the birth as my first was very straightforward with no complications but I am scared now. Does SPD make labour much more painful and difficult?
Finally I know it should go away when the baby is out but the thing I am most scared about is not regaining full pain free mobility afterwards so positive stories and reassurance would be appreciated.
I am only 25 weeks so I now have 15 weeks of pain to look forward to
