Sayang, please go to the hospital or call your doctor/midwife right now, don't wait , especially with the coloured discharge at 38 weeks. Better to get checked and feel sure than worry at home, honestly. A few of us mums have been there and the doctors always say it's better to come in early than risk something; they won't scold you for coming, I promise. Your baby is ready anytime now, and that discharge needs proper checking, could be nothing serious, but it needs eyes on it today, not later. Don't worry about early admission lah, health comes first!
