Kerri, does sound like spd, classic signs are pain on turning over or getting in and out of bed and as for pushing things across the floor with your foot - don't know about you, but that's 'really' painful for me - typical isn't it, you can't bend over the pick anything up and can't move it out of the way without bending over - ah pregnancy is such fun!
I would recommend speaking to your mw asap as if they can arrange for you to have a belt and some physio you may be able to prevent it getting any worse. They can also advise you on the ways of stopping it getting any worse, such as Knickers said, keeping your legs together when you turn over, also take smaller/shorter footsteps, try not to lift anything too heavy (I know not always possible) and always try to sit or stand squarely rather than favouring one or other hip. One good thing though, vacuuming is not recommended so my DH is having to pull his weight as with 3 dogs our house needs constantly vacumming!
Alternatively a visit to a good osteopath has been known to work wonders. Basically they are able to realign your spine and pelvis so that things are back in the right place and not clicking or grinding. Some people with mild cases find one appointment is enough, others attend once every few weeks to keep things together so to speak. I'm not sure how much it costs elsewhere, I am in the midlands and here it costs £50 for an initial consultation and session then £45 for any sessions after that. Like I say, don't know if that is a typical price, but I would gladly pay double now I know the relief it can give.
