Oo normal lang yan, mama! Yung sore breasts ay usually mas malakas sa first trimester pero naturally napapababa siya as your body adjusts, a few of us na nag-share sa group namin lahat nag-experience ng ganyan around weeks 11-12, kaya hindi ka nag-iisa. Pero since every pregnancy is different, if you're still worried or may sudden changes na out of the ordinary, good idea to mention it sa OB mo sa next checkup para peace of mind lang, kasi overthinking during pregnancy is real haha. You're doing great!
