Sayang, clear mucus kat 38 weeks bolehlah normal, tapi kalau ada rasa tak sure, better gi check with your doctor or midwife je, tak payah tunggu lagi. They can confirm if it's just the usual discharge or something else, especially since you're so close to due date na! Kalau suddenly ada bleeding or sakit perut teruk, pergi hospital tau, jangan delay. A few of my mum friends said they went in to confirm, better safe than sorry kan? Take care!
