Ay sis, sobrang confusing talaga yan lalo na may symptoms ka pa, pero honestly ang best move mo talaga is mag-consult sa OB para sure na, kasi PT can be negative pa even if pregnant, especially if testing too early, at yung symptoms mo (nausea, pagod, frequent urination, cravings) could be pregnancy OR side effects ng pills or hormonal changes. May kaibigan ako na ganyan din, nag-pills, nag-miss ng period, pero it turned out hormonal imbalance lang from stopping the pills suddenly, kaya kailangan talaga ng blood test or ultrasound para malaman, don't stress muna, pero don't delay the checkup din okay? Keep us posted!
