Need some reassurance or information! 😩

My husband and I are expecting our first baby, boy, in September. We are currently 21 weeks and had our 20 week scan last week. We got a call from the doctor that said everything looked normal on the ultrasound but the kidneys are a bit dilated. She was very reassuring as it can be common in boys and often resolves on its own. We have to have another scan at 30 weeks to check again. Just wondering if any mama's have had happen? And how it turned out? Just a first time mom over here who HATES medical stuff and just want to talk to fellow moms about it. Thank you!
