Uy, nakakaguluhan talaga yan, positive sa mahal na PT tapos negative sa murang PT, paano ba yan? Honestly, marami sa amin na nagkaroon ng similar situation, and usually it's either timing ng test (sometimes kunti lang ang hCG pa), quality ng test kit mismo, or kailangan lang ulit-test after a few days para confirm. A few of us tried buying different brands din kasi, and yung murang ones talaga ay sometimes hindi kasing-sensitive, lalo na if very early pa lang. Best move is mag-ulit test after 2-3 days using the same brand na nag-positive, or go straight to clinic para sa blood test para sigurado na talaga!
