Sayang, this is really something you MUST discuss properly with your doctor or go to the hospital sekarang juga, okay? At 34 weeks with cervical opening and contractions, your situation needs professional monitoring, bukan boleh guess-guess online. A few of my mum friends ada gejala macam ni, and honestly, doktor mereka explain better once they see the full picture, whether it's preterm labour, how the medication works for your specific situation, or what comes next. Every pregnancy lain, and at this stage kena follow your O&G's plan closely. Jangan delay, sayang, go see your doctor or head to the hospital for proper assessment. Take care of yourself and baby!
