Sayang, keputihan coklat ni banyak sebab-sebab, and some bisa normal tapi ada juga yang perlu check dengan doctor. Because it involves your reproductive health, please go see your gynae or go to a clinic/hospital to get checked out properly, jangan tunggu lama-lama ya. A few of my mum friends ada kena, some turned out normal hormonal changes, ada yang perlu treatment. Doctor je yang boleh tengok betul-betul and tell you exactly apa yang happening. Jangan risau tapi jangan delay jugak, go get it checked out okay?
