Echogenic focus

H
Has anyone else delt with an ultrasound showing an echogenic focus on the heart. I know in most cases it's nothing but I can't help but worry. The nurse we talked to (or Dr was on call) said everything else looks fine and I should be like 90% not worried, cuz she said they can't tell you 100... But is still sending us to another facility on monday to get another look. We are 24 weeks and declined all other prior testing. Ftm and rainbow baby so maybe I am just being extra nervous, can anyone give advice? Does everything look ok in these photos? Any input would be nice
