Help my anxiety on Unilateral ventriculomegaly

Knottie50633263

3rd pregnancy with polyhydramnios. With my first two pregnancies(girls) my polyhydramnios was idiopathic and I had healthy baby girls. 28 weeks re diagnosed with poly and the doc explained to me there is a possible diagnosis of Unilateral ventriculomegaly as the number is at 10. Which is just at the high normal range. Now he explained how it could fix itself and could just be cause of my fluid and the baby is big already. I’m reading stuff online and it’s so scary and not helping my anxiety. Won’t know about the number again until another scan in 2 weeks. Can anyone shed some light on this? I’m so scared.
