Okay so I went for my 20w ultrasound last month, but needed to do it over at 23w so that they could get better measurements of my baby's spine...now I am 25w3d and just left my doctor who informed me that fluid was detected around my son's heart. She didn't go into detail, and also didn't seem worried, but referred me to have an echocardiograph done in a week or so. My son's heart rate was perfect, and no other issues we're addressed. Has anyone else experienced this? I've read a few articles stating that most of the time it fixes itself, but I am still freaking out. Thanks ladies.
