We are having a boy!

We found out this morning that our first child will be a little boy! We are so in love! He is 14oz at 20weeks 5days. Everything looked good from a developmental standpoint except he has some fluid backing up into his kidneys. They told us that it is fairly common and not necessarily cause for concern yet. I have to go back at 32 weeks for them to see if the issue still exists. Anyone else have experience with this? They also are checking me to see if I am a carrier of Fragile X Syndrome bc I have a cousin with a son who has Autism. Hoping I am not a carrier and that our baby is healthy!
