Ay common yan sa pregnancy, lalo na as you progress! A few of us mums experienced hip at pelvic pain during the second and third trimester, especially pagod na from the day kaya naramdaman mo nang gabi. Pero since you're still early (10 weeks), better check with your OB just to be safe, sometimes it's ligament stretching, sometimes it's position-related, at gusto mo lang masigurado walang iba. In the meantime, try sleeping on your side with a pillow between your knees, super tumutulong yan sa amin dito!
