Aih sayang, 33 weeks memang period yang sakit sangat, pregnancy hormones and baby's weight ni semua berat kat tulang belakang kita! A few of my mum friends swear by maternity support belt (the ones from Mothercare or even drugstore punya ok), pakai from morning sampai evening really helps spread the weight. Try juga posisi tidur guna bantal kat bawah perut dan between your knees, and maybe ask your husband massage gentle-gentle kat area tersebut, pastu avoid berdiri lama or sitting dalam satu position. Tapi kalau sakit dia sampai terasa berdenyut and affecting your walking gait, better check with your gynae or midwife sebab could be nerve pressure or something else yang kena monitor. Hang in there, mummy, soon baby will be out and the relief is real!
