Uy momsh, please don't take those, expired pills (lalo na ng matagal na) can lose potency or change chemically, at with birth control especially, hindi ka dapat mag-risk! Better to ask your OB or pharmacist kung pwede pang gamitin, or get a fresh pack na lang para safe and sure ka. A few of us moms learned the hard way na hindi worth the gamble ang expired meds, especially contraceptives na kailangan consistent at effective talaga. Talk to your doctor agad, okay?
