Congratulations on the positive UPT! Tapi memang boleh ada spotting awal-awal pregnancy, terutama kalau implantation bleeding, a few of my mum friends experienced brown discharge dalam first few weeks dan they were all pregnant, so jangan panic dulu lah. The best thing is to book an appointment dengan doctor or clinic so they can confirm with a blood test or ultrasound, especially sebab timing-wise it's still very early; doctor can reassure you properly about the brown spotting and make sure everything is okay. Wishing you all the best, dear!
