Sayang, brown bleeding in early pregnancy can be normal sometimes, but please go see your doctor or go to the clinic today to check, okay? Better safe than sorry at this stage. A few of my mum friends had brown spotting early on and it turned out fine, but some needed extra monitoring, so really best to get checked properly lah. Good thing you already did a scan yesterday and saw the sac and yolk sac, that's reassuring, but your doctor needs to see you again to make sure everything is progressing well with the bleeding. Jangan tunggu-tunggu, just go in and let them have a look. Thinking of you!
