light spot on heart in ultrasound

Da
So I had my gender reveal ultrasound and 16weeks 4 days and found out I'm having a boy was very excited but as the checked out my babies health he seemed really healthy all in all but they found a light spot on his heart so called my doctor once my doctor spoke with them she informed me this is usually a common thing they see in ultrasounds but mine looked much different then what they usually see so now I'm worried to death my baby will have heart problems and am waiting to get scheduled with a specialist who comes to my city once a month in so nervous in the mean while waiting for more information it's all I can think about anyhow I could really use some prayers from people it'd be highly appreciated thanks
