Aiyooo 35 weeks, memang sakit belakang lah mama, I feel you! A few of us pregnant mummies tried wearing a maternity support belt (can find at most pharmacies or online), and honestly it helps ease the pressure quite a bit, especially when walking or standing long. Also try gentle stretching, warm showers, and sleeping with a pillow between your knees, my mum friends swear this makes a difference for lower back pain especially. But if the pain gets really bad or you're worried it's something else, better check with your doctor or gynae just to be sure everything's okay, aite? Tahan je lagi a few more weeks, you've got this!
