Ladies I need advice on how my delivery should be:

Right now I have the option to do a c-section or a vaginal delivery. I’ve had 3 babies vaginally, all got longer and harder each time. Not the concern. The concern is that after baby number 3 and before baby number 4 (current pregnancy due August 1st) I developed a heart condition. My ob keeps telling me I have the options, however, my cardiologist keeps saying, it’s to much strain on my heart. What do I do!!!??

And any advice on a c-section? I’ve obviously never had one, and am extremely nervous about having one!

TIA ladies!! ❤️
