hi there, i was diagnosed with heart murmur when the little one is at week 23. was sent to a cardiologist for a detailed heart scan but ruled out any major issues. heart murmurs can occur as a result of pregnancy. as long as the cardiologist clears you, it's not something to worry about. although i do feel breathless and a heavy thumping sound in my ears when i climb stairs.
my little one is now 7 months old but i have not reviewed to see if my heart murmur is still there.
