Sayang, discharge campur sikit coklat masa pregnant memang boleh jadi, tapi since you're only 13 weeks in, better safe than sorry, please call your doctor or go to clinic hari ni je untuk check, okay? They can confirm everything's fine and put your mind at ease. A few of my mum friends went through similar scares early on, and sebab tu lah doktor always prefer to see you to rule out anything. Don't worry sangat, tapi jangan delay check up, mana tahu kan, better get professional advice straight away. Hang in there!
