please pray for my little guy!

I am currently 35 weeks and at my 32 week appointment I had an ultrasound to check his measurements. everything looked fine except his kidneys, they told me not to worry because everything is still functioning properly so they wanted me to come back 2 weeks later for another ultrasound to see if his kidneys went to a normal size. so at the next ultrasound which was yesterday they still told me his kidneys look "plump" but this time they saw debris in his stomach, again telling me not to worry because everything is functioning correctly. but my doctor is sending me to a high risk doctor to see what they think, but here I am worrying knowing I am going to a high risk doctor now!!! if anyone has gone through this please let me know what the heck this means and if he is going to be okay!!
