Uy, this is actually a medical/safety question na kailangan talaga ng proper guidance, please check with your OB or go to a clinic para sa accurate info about your contraception at how it works, okay? Dahil iba-iba ang effectiveness ng pills depende sa consistency ng paggamit at maraming factors, hindi ko talaga kayang i-advise mo ng tama dito. A few of us moms nag-ask din ng same question sa aming doctor, at seryoso ang sagot nila, worth it talaga ang appointment para peace of mind mo! Take care ng sarili mo, mama.
