Ay, sis, this is definitely a doctor's call, hindi ko kayang sagutin ito properly kasi it really depends sa specific condition mo at how your heart is doing ngayon. Please please consult with your OB and a cardiologist din if possible, lalo na kung serious ang condition, they'll know what's safest for you and baby. A few of my mum friends had complications during pregnancy, and honestly, ang doctors lang ang nakakasiguro kung normal or CS talaga ang kailangan. Don't stress pa muna, focus muna sa checkups mo, okay? You've got this, and ang medical team mo ang best guide mo dito.
