Oo, posible talaga kahit nag-take ng pills, hindi 100% foolproof ang anumang contraception, lalo na kung may missed doses or other factors. Best thing is to see your OB para ma-clarify ang effectiveness ng Daphne at kung naka-take mo siya correctly, kasi maraming variables dito. Kung may signs ka ng pregnancy na, get a test done para alam mo agad, okay?
