Sayang, I understand you're worried! But honestly, this is something you really need to ask your doctor or gynae directly, they know your full situation best, especially since you're post-C-section. Contraceptive reliability can vary from person to person, so better to get proper medical advice rather than guess, kan? One of my mum friends was in similar boat after her surgery, and her doc explained everything clearly, put her mind at ease. Don't stress alone lah; a quick call to your clinic or even ask during your next checkup. You deserve proper answers, not forum guessing!
