Uy, first thing, please don't wait if baby shows any breathing trouble or bluish lips, okay? Go to emergency right away. But if baby seems okay and you're just waiting for consultation, breathe, mama. Heart concerns need proper imaging and specialist eyes, hindi kami kaya i-diagnose yan sa bahay.
A few of us mums have gone through scary-sounding scans din, and honestly, ang doctors talaga ang mag-e-explain ng severity at options. Next week is coming soon, write down your questions now so you're ready, and try not to Google too much (I know, easier said than done!). You're doing the right thing getting professional help. Rooting for you and baby.
