why I am feeling breathless after 5 months of delivery n heart ke pass kbhi kbhi flickering bhi hoti h kya h kuch tension wali baat h ya normal h

A. Peripartum cardiomyopathy is a weakness of the heart muscle that begins during the final month of pregnancy through about five months after delivery, without any other known cause. Most commonly, it occurs right after delivery. While it's relatively rare peripartum cardiomyopathy can be life-threatening.
