harrassed, can't see why you couldn't have a home birth with SPD/PGD. Esp if you are planning on using a birth pool / this is not your first and previous were ok. Might be worth asking for experiences on childbirth forum??
lilBB - I'd forgotten my hip used to seize up actually! Just remembered, as it was right at the start (came on at 8 weeks) before I had the wit to slow down and rest! Cutting way way way down on driving really helped. Used to lurch around twisted to one side like Quasimodo. Hideous - but it did settle. A month off sick sitting on the sofa taking it easy went a long way to sorting it - tho driving / sitting in blimming traffic or walking and being on my feet alot are all recipes for trouble.
shono - hee hee that advice is up thread, most physios forget about that bit!! VERY important safety tip ta, all are appreciated as whiplash on top of SPD would be sh*te. BTW, my pelvis doesn't seem to have slipped to the side since sleeping with a support pillow between my legs.
sarah - glad to osteo helping. Think the best thing is when you feel someone is helping and taking you seriously, rather than either dismissing you or patting you on the head going 'there there, it's awful isn't it but hey ho it'll go when the baby comes.' Yes. thank you. I know that is what usually happens but this is horrible and really impacting on my life and I hate you because you should have a bloody magic wand to make my PGD vanish!!!! But that usually doesn't happen

iwill - sounds like you're having a bad week, hope things are getting better (for you and DD!). I'm 33 weeks too, it seems so close and so far away at the same time. Happy to say I've been at baseline soreness this week. However, the little bugger darling in my tum and hit on a new wizard wheeze to amuse himself. He is quite a little wriggler, so will turn around from transverse to vertical but has now discovered the joy of lying oblique, with his feet under my ribs on the right and his head (or arms) braced on the right front half of my blimming pelvis and pushing on both. Tis really really unpleasant!!!
sueflay - welcome onto the birthing ball. You sound like you already know your midwife is talking out of her arse. Ring the physio department yourself and ask them what their referral procedures are, hopefully you can wave this in your mw's face next time!!! most physios will insist the earlier the better so waiting til 20 weeks is insane. Insane I tells ya. and yep, it's been rebranded to take into account the whole pelvis can be wibbly but most people still recognise SPD best.
Whingers are aways welcome here, tis actually mandatory to let it all out here 
as you can see on the basis of this mammoth post. Sorry folks...
