Salam sis! Sakit punggung awal pregnancy memang common sangat, a few of us experienced it juga, some of my mum friends kena worse lagi. Boleh jadi dari hormones yang relax ligaments, or posture changes sebab body adjusting. Tapi sebaiknya mention to your doctor just in case, especially if it's really bad or ada symptoms lain, some things perlu ruled out la. Meantime, rest yang cukup, warm compress, and try not to lift heavy things memang boleh tolong!
