Alah jangan risau sangat lah, tu normal je! Early pregnancy memang macam tu, HCG positive tapi kantung belum nampak lagi boleh jadi because dating is off or baby baru attached, especially kalau period cycle kau irregular. Few of my mum friends pun sama situation, rupanya baby ada, just timing scan aje yang awal sangat. Doc pasti akan suruh kau balik dalam seminggu or two untuk rescan, that's the standard move, so just follow up dengan dia je dan try relax (I know, easier said than done!). Hang in there, mummy dah dapat positive, that's the important part!
