Sayang, any spotting or bleeding in pregnancy kena check dengan doctor dulu ya, even if sikit je. Don't wait till 8 weeks, call your clinic or go in sooner, boleh je they scan you earlier untuk peace of mind. I know it's scary especially first baby, tapi better safe than sorry, kan? Some spotting boleh okay, but only doctor boleh tell you properly after scan. Jangan risau dulu, go get checked tau, you deserve to know baby is okay!
