Sayang, situation macam ni memang scary dan confusing. Tapi honestly, kena jumpa doktor lagi sebab yang ni bukan straightforward, bleeding dalam early pregnancy tu serious, dan scan tak nampak kantung even at 6 weeks by LMP kena follow up properly. Doctor tu kena check if it's progressing normally, ectopic, atau memang miscarriage. A few of my mum friends yang pernah through similar thing, dorang kena repeat scan a few days later sebab timing tu tricky, sometimes kantung memang belum visible yet, sometimes the dates are off. But doktor perlu confirm either way, especially sebab ada bleeding dan previous pregnancies were normal. Don't wait, go back and ask for follow-up scan in a few days or get a second opinion from another gynae. Your peace of mind matters, and this needs proper monitoring. Sending you strength, mummy.
