Only 17 weeks & having a lot of pains

It hurts to walk, sit, stand, roll over.. The pain is at the sides of my vagina, feels like the bones there are sore. This started early, like 12 weeks, but its gotten a lot worse recently. And now my lower back is starting to hurt. My ob office still hasn't called me back about it. From what I have looked up it may be spd? But I'm so worried having it this early, it's usually near birth from what I've read... Wondering if anyone else has had this problem?
