Ehhh I totally get the anxiety ni, memang parang cau betul bila period delayed and upt negative kan. A few of my mum friends pun pernah kena situation mcm ni, sometimes hormones just act up, stress pun boleh delay things, or maybe timing upt-nya belum tepat lagi (HCG levels mmg belum cukup tinggi early on). Since your doctor already said tunggu 2 weeks and test again, that's actually the smartest move, better to wait a bit than keep stressing yourself out, and hopefully by then je clearer lah apa situation sebenarnya. Just try to relax, stay calm, and if the 2-week mark comes around and still nothing, balik je jumpa doctor lagi, okay? Fingers crossed untuk you!
