Uy momshie, tanong lang, sigurado ka na ba na okay lang mag-switch ng brands based sa doctor's advice mo? Para sa ganitong contraceptive concerns, kailangan mo talaga mag-consult sa OB mo first, lalo na kung gusto mong malaman kung kailangan ng waiting period or backup protection. Iba-iba kasi depende sa ingredients at timing ng switch, at hindi dapat guesswork lang yan. One of my mum friends had the same worry, at sabi ng OB niya may specific instructions depending sa cycle niya, kaya better safe than sorry talaga. Give your doctor a quick call or text, okay? They'll give you the exact timeline para walang worry ka!
