I feel the very same pain. I've had it since about 12 weeks and I also had it last pg.
I saw the physio at Caboolture hospital yesterday and have now ordered a brace support thingy. It felt so good when she strapped me in cause I am in severe pain 24/7.
Just a few tips to help with the pain, whenever you change position or get up and down, clench your buttocks and pelvic floor muscles. Since doing this yesterday I can get up off a seat or the bed with greater ease.
Another thing is regular massage.
I have now been pretty much put on rest as there is nothing that can be done about it, it's just unfortunate the the relaxing hormones released during pg have gone a bit over board.
HTH, good luck and take care of yourself.
