Sayang, brownish discharge tu memang boleh jadi normal during pregnancy, tapi at 29 weeks kena alert sikit, especially kalau ada cramping, bleeding, or rasa tak right. Please go see your doctor atau midwife ASAP to check , better safe than sorry! A few of us moms had similar things and it turned out okay, tapi doctor kena examine properly to make sure baby and placenta okay. Don't worry too much, just get it checked quickly, okay?
