Soft markers

Hi my name is Syreeta & I'm 23 weeks pregnant & we just found out it's a boy. 😁. I'm just nervous because the doctor said he had two soft markers for Down syndrome. He had 4 and a half millimeters in his left kidneys and the cut off is 4. Also he had a white marker in his heart. Should I be freaking out or should I relax. I'm waiting for the test results to come back any day now.
