Ay, honestly mama, kahit breastfeeding kayo, possible na bumalik na ang period, nangyari din sa akin around 3 months postpartum kahit nag-breastfeed ako! But at 2.5 months, it could still be lochia na may random spotting, especially if may activity ka or pagod ka lately. Better to message your OB lang about it, lalo na kung concerned ka sa heaviness or kung mag-continue pa, para ma-rule out any complications at ma-peace of mind mo agad!
