Wa'alaikumassalam sis! Spotting early pregnancy memang boleh normal, tapi since you've had it for almost a week, you really need to see your doctor or go to klinik as soon as possible lah, tak boleh tunggu. Better safe than sorry, especially at 6 weeks. A few of my mum friends dulu ada spotting tapi betul-betul kena check dengan doctor untuk confirm everything's okay. Go lah sekarang jangan delay!
