Uy momsh, totally normal yan! A lot of us mums noticed na after delivery, lalo na kung hindi breastfeeding, ang flow namin either naging lighter or mas heavy for a few months kasi ang hormones mo ay nag-aayos pa lang after pregnancy. Basta kung hindi ka nag-aalala sa pain or kung may weird smell or clots na malaki-laki, siguro okay lang yan at babalik-balikan pa ng katawan mo, pero to be safe I'd still mention it sa OB mo next checkup para peace of mind. One of my mum friends said hers went back to normal after around 3-4 months, so give it time din!
