You're probably testing a little too early, momsh. If too early pa sa pregnancy like 2 weeks or less than 3 weeks, the hCG level in your urine is only enough to be detected that's why you will see a faint line na will disappear lang after a period of time (not sure how long bago mag disappear). You can try another PT to test again or best test again after around a week or so ☺️
