Heart trouble

I have had a heart condition for years, was told to put off ttc at 20, had surgery to correct my heart at 25, and then was told I could start ttc. I'm 36 now.

Last week I found out my heart is not doing as well as it should. I was told that I need to put off ttc until we have further test results.

I'm scared. I really hope it's ok and that I can start ttc again.
