Has anyone been tested for CMV?

Hey everyone I’m pregnant with my second due in April next year I’ve been tested positive for cmv I didn’t even know I had it nor do I even know what it is I was meant to be having my 20 week scan on Friday now it’s been pushed to 29th of this month as i now have to see a specialist. I’ve been googling it all day and it’s made me into a mess and I wanted to know if anyone has tested positive for this being pregnant have had babies with it I’m so scared and need someone to talk to
