Eh betul lah tu boleh jadi! Especially kalau test terlalu awal, hormone HCG belum cukup tinggi lagi so the UPT shows negative padahal actually pregnant. A few of us moms actually went through this, one of my friends did UPT three times negative, pastu scan showed baby sudah ade! Kesian dia, stress je tunggu. That's why doctor usually akan ask for blood test or scan kalau symptoms ada tapi UPT negative, sebab blood test lagi sensitive and accurate. So jangan sedih, confirm dengan doctor and blood test je memang lebih reliable
