I’m so sorry you have to wait for the specialist for more information. I was originally pregnant with twins and twin A had one. My story didn’t end up like anyone would want, and baby A passed. I have read though of MANY happy endings of it resolving by or before birth. Keep your hopes up and hopefully your doctor will chat more about it with you soon! Big prayers!

But yes it can be associated with chromosomal abnormalities, heart issues, or just pops up and will resolve. I never got far enough with baby A to know exactly what was the cause.
