Uy, ang heartburn during pregnancy talaga sobrang kukulit, lalo na ngayon ka pa lang 3 months in! Honestly, mas okay kung maghintay ka ng konti after you feel the nausea bago kumain ulit, pero dapat talaga doc mo-check mo yan kasi ang panininikip ng dibdib mo sounds like it needs professional advice, maraming mums sa circle ko na ganyan, at the doc gave them safe meds na tumulong talaga. In the meantime, try eating smaller meals more often, avoid spicy or greasy food, and sleep propped up with extra pillows, pero please consult with your OB soon kasi alam mo naman, better safe than sorry during pregnancy. Wishing you relief soon, mama!
