Fluid around heart

Mel

I am really nervous right now. I had an ultrasound today at 19weeks 2 days, I was really excited because we were getting the gender and having them put it in an envelope for our reveal party in a week. They said everything looked good on ultrasound, including brain, body size, stomach, spine, hands and feet even the heart and heart beat looked normal except they thought they might see a small amount of fluid around the heart. I have a follow up ultrasound in 2 weeks but I can’t help but freak out and worry, any body have similar experience or advice to help me from freaking out. I’m so scared.
