Eh sabar jangan panic dulu! Kalau UPT samar-samar memang sometimes boleh jadi line melemah atau hormon belum naik cukup lagi, terutama kalau test terlalu awal selepas ovulation. One of my mum friends pun dulu dapat faint line, then negative, then positive, hormone HCG kan naik gradually, jadi timing test memang penting. Sebab the digital test sometimes needs higher hormone level to show positive, lagi-lagi kalau urine dah dilute lepas bangun tidur pagi, so yang first UPT tu lagi accurate kalau garis tu nampak. Better call your klinik balik and book an ultrasound ke, that's the only way to confirm betul-betul. Don't stress yourself lah, we've all been there second-guessing!
