Ay sis, normal lang yan especially kapag pure breastfeeding ka pa, ang nipple stimulation talaga ay nakakaapekto sa period, kaya madali lang mag-skip or mag-light lang, lalo na kung solid ang milk supply mo! A few of us moms sa circle ko the same experience din, some didn't get their period back for almost a year or two habang nag-breastfeed, so walang alala doon. That said, mas safe pa rin magcheck with your OB just to be sure everything's okay, especially since you're on Daphne, they can give you peace of mind and check kung ano talaga ang nangyayari sa hormones mo. Keep taking your pills as prescribed naman
