It definately sounds like spd, I have had it with all my pg and # 3 was quite bad and i had to wear a brace and this time it has started already, ive been to the chiro and had massage to help as i could hardly walk last week.

At least you don't have too long to go now so that is good.

I find sleeping with a pillow between my legs help and keep your knees together when you roll over in bed.

Also when getting dressed make sure you sit down when putting your legs in your pants etc as lifting one leg up is excruciating and can really aggravate it.

That crunching is horrible. You can get pain in the groin, butt and down your legs.

I find heat packs are good and if possible stretching the hamstrings/butt. Also don't stand up for too long, make sure you have plenty of rests.

Good luck xox
