Sayang, brown discharge masa pregnant memang boleh terjadi, tapi sebab ni sensitive and important untuk baby, please see your doctor or go to clinic asap, jangan tunggu Better safe than sorry, especially at 10 weeks. A few of my mum friends had similar experiences and turned out fine, tapi each pregnancy lain-lain. Your doctor kena check properly to make sure everything okay. Jangan stress sangat dulu, tapi do get it checked out immediately ya?
