20wk scan/baby’s kidneys

Mariah

I had my 20 wk scan last week & everything looked great. The only thing the dr said was that the baby’s kidneys had some fluid which she said is normal at this point in my pregnancy and she wasn’t concerned but well do another ultrasound in 3 months to check on it. She said it wasn’t life threatening & I was fine with her answer because my nephew had something similar before he was born & is fine. I came across an article about if my salt intake is too high it can mess with the baby’s kidneys so I can’t help but feel guilty. I don’t eat fast food every day, maybe once every 1-1.5 weeks.. I’d like to think I eat pretty decent, it could definitely eat way worse & I drink plenty of fluids... any thoughts or am I just being crazy?
