Ahhh normal je sayang, especially at 29 weeks! Baby dah besar dan positioning dia memang akan tekan area bawah, so achy aching tu very common first trimester pregnancy thing. A few of us dalam mom circle went through the same, one friend swore that wearing a maternity belt helped her support the weight better, and another just made sure she sit down more and walk slower je to minimize the discomfort. Try gently stretching, rest when you can, and maybe lie down on your side when the heaviness feels too much. But since this is causing you concern dan you're noticing it's affecting how you walk, best check with your doctor just to be safe, they can confirm everything's okay and maybe give you specific exercises or support that works for you, ya? First time mom anxiety is real, no need to apologize!
