Ay, kailangan mo talaga mag-check with your OB/GYN agad, sis, kahit negative ang PT, may iba't ibang reasons kung bakit delayed ang period after stopping pills, at better safe than sorry talaga. A few of us mums noticed na ang cycle namin took weeks or even months to normalize after stopping contraceptives, but since you're worried at it's been a while na, don't wait, your doctor needs to check kung okay lang everything or if may iba pang concern. Hoping it's just your body adjusting pa lang, pero get that peace of mind soon!
