Oo normal yan, mama! Ang lactation talaga nag-aaffect ng cycle, especially if you're exclusively pumping/breastfeeding, a few of us tried mixed feeding and delayed pa rin ang period for months, kaya don't panic. But since nag-do na kayo ni hubby, better check with your OB just to be sure everything's okay, lalo na kung worried ka na, peace of mind lang yan, at makakatulong din sila mag-confirm if it's just the breastfeeding or something else.
