Sayang, ini betul-betul kena follow up dengan doctor, short cervix ni bukan main-main dan kena monitor closely, especially kalau ada risk early labor. A few of my mum friends went through similar worry, and honestly the best thing was regular scans and follow doctor's advice exactly, some kena bedrest, some kena progesterone, tapi setiap case lain. Please jangan delay appointment, okay? At 29 weeks, timing ni crucial. Your doctor akan tahu best step untuk keep baby safe inside longer. Sending you strength, mama, hopefully everything stabilizes!
