Aaah sis, I totally get the anxiety na yan, sobrang stressful talaga pag ganyan! Usually mas reliable ang PT pagka-7 to 10 days delayed na, kaya if gusto mo mag-test ulit, maybe wait a few more days pa para sure ang result, pero honestly the best thing is to see your OB na para ma-rule out ang iba pang reasons why delayed ka (stress, hormonal changes, thyroid issues, etc. ay common din yan), may mga kaibigan ko na delayed ng weeks dahil sa stress lang, kaya don't panic yet sis. Rooting for you, let me know what your doctor says!
