Aw, congrats on your baby! Pero honestly, three weeks pa lang kayo and you're experiencing pain sa puso at tagiliran, better get that checked with your OB or doctor agad, ha, kasi baka postpartum stuff or something else na kailangan tingnan ng professional. A few of us mums went through similar discomfort after birth, pero depends talaga kung ano ang cause, so don't wait na, mapanatiling safe ka para ma-enjoy mo ang bonding time with your little one. Sending strength, mama!
