Uy, I totally understand your worry, mama, that's a valid concern talaga, pero honestly, this is something na kailangan mo talaga i-discuss with your cardiologist AND OB together, ha? They need to know your full heart history para ma-plan nila ang safest way for you to deliver.
A few of my mum friends have had similar cardiac concerns, at ang sabi nila, once na na-coordinate ng doctors nila yung care, naging mas okay ang kaba nila kasi alam nila ang exact plan. You're not alone in this worry, maraming mamas with heart conditions have safely given birth, pero ang key talaga is proper medical supervision from both specialists. Please schedule a consultation with them ASAP if you haven't already, pati na rin siguro ang anesthesiologist para sa full picture. Kaya mo yan, mama!
