Eh normal je tu in pregnancy, especially dekat pelvis area, a few of my mum friends had the same thing around that time, bunyi tapi takde sakit so we weren't worried lah. Ligaments dan joints kamu relax sebab hormone relaxin, so bunyi-bunyi gitu memang boleh jadi especially kalau banyak bending or changing positions. Tapi since you're at 9 weeks, mungkin baik mention to your OB next checkup just to make sure everything's fine, tak perlu panic but good to confirm dengan doctor sebab dia boleh examine properly!
