Sayang, UTI (kencing kotor) memang boleh trigger contractions, so jangan delay, please go see your doctor or go to hospital sekarang jugak, especially at 33-34 weeks. They need to check if baby is okay and give you proper treatment. A few of my mum friends kena sama, and the doctors sorted them out with safe antibiotics yang okay during pregnancy. Don't worry, early intervention is better! Keep me posted ya, thinking of you.
