Hi, I recently had my 19 week ultrasound and I was given the report and have a few questions. What does hypoechoic area inferior tip of placenta ? Marginal sinus 3.6x 0.8x4.3 cm. cord noted inserting 2.08cm from left superior placental edge mean and how does it relate to my baby s health. Second, what is the cavum septum pellucidum, it was suboptimally visualized, and again how does that relate to the growth and development of my baby? Thank you so much for your time
