Euro, I'm thinking about it.
To those with early signs of SPD, my yoga instructor has talked about the importance of strengthening the muscles around the hips and flexors to make up for the ligament stretching. Doing warrior poses, squats, leaning against a wall and moving your leg in a circle to the side or doing leg lifts can all help. That's what lets you walk straight instead of waddling later on. I would strongly recommend an active prenatal yoga class to anyone who can find one in their community. Or prenatal aqua classes for those who are hurting a lot.
Good luck! Tray - my hips are super painful at night too. The yoga is helping a little, but not a lot!
