I was wondering in anyone is in a similar situation or has been as my ultrasounds with my 2 previous kids were completely normal.

I had my anatomy scan last week and I was told everything looked perfect with our little girl except they saw a small shadow on her left kidney that they want to look into more. I was told it could be possible calcification and not much more info than that. Of course I'm super worried. I've googled this and haven't found much of anything. To make matters worse is that my MIL thinks the reason for this is because I took zofran in my first trimester.

My midwife has referred to maternal fetal and I'm getting another ultrasound in a couple weeks when I'm in my 23rd week to look into it more so we'll have more answers then.
