Oo mama, super normal yan! A few of us in our mom group are in the same boat, ang breastfeeding talaga ay nagpapakompas ng period kaya pwedeng delayed or wala pa talaga for months, especially kung exclusive breastfeeding pa. Pero since 5 months na at medyo matagal na, better check with your OB just to be safe, para makita kung ano talaga ang nangyari and kung kailangan mo ng anything, lalo na kung hindi ka using protection pa. Take care!
