Aih, normal je 14 minggu rasa sakit pinggang, uterus dah membesar and the extra weight puts pressure on your back, plus hormone relaxin is loosening your ligaments, so your body is adjusting gila-gila. A few of us moms went through the exact same thing, ada yang pakai maternity support belt, ada yang rajin stretch atau swimming, tapi sebab involve pregnancy, better check with your doctor or midwife to make sure nothing else going on, especially kalau sakit tu makin teruk or ada symptoms lain, okay?
