Uy, I feel you mama, a few of us in my mum group dealt with this din, and it's honestly so uncomfortable na parang gumagalaw lang ang pelvic bones mo hehe. My friend swears by a pelvic support belt (yung matibay na stretchy one from Lazada), and honestly it helped her a lot with walking and getting in/out ng car, plus she did some gentle prenatal stretches na pinapakita ng physical therapist. Since your OB said it's normal but noted it's early, I'd really suggest asking her for a referral to a physio or getting a second opinion kasi if it's affecting your daily life na ganitong aga, might be good to have someone specialize in it, hindi ka naman dapat mapagod na ganito for the next 11 weeks pa lang! Hugs mama, you've got this.
