Sayang, at 36 weeks macam ni memang boleh jadi Braxton Hicks (false labour) sebab badan sudah prepare untuk bersalin, tapi kalau dah dua malam terus-menerus dan contraction pattern dia tak consistent macam ni, you really should call your doctor or go to the hospital today to check, especially since you're worried. Better safe than sorry kan, terutama at this stage! A few of my mum friends kena macam tu jugak, and doktor aje yang boleh confirm properly through examination. Don't wait lagi, just go get checked, okay?
