Sabar je dulu mama, period biasanya lambat datang kalau fully BF, it's normal! A few of my mum friends took Noriday while BF-ing and they said susu still okay, tapi best check with your doctor or lactation consultant first sebab setiap orang lain-lain kan, especially kalau breastfeeding is going well right now. Ada jugak some of us yang prefer tunggu period datang dulu before starting any hormonal pills, just to be safe. Congrats on the baby and good luck dengan family planning!
