False Negative o False Positive?

1st PT ko negative after how many hours biglang may sumulpot na malabo, sobrang labong line. Nag try uli ako sa 2nd PT this past few days lang negative uli ng morning then evening biglang may sumulpot uli na positive line pero kaso Mmdyo malabo pa din. Ano po kaya ulitin ko ba uli mag PT? 🥹
