Soo worried 😭

I just need a place to vent. At my 20 week scan i was told my babys kidneys were slightky dialated at 5.5 mm they told me not to worry it usually resolves itself... we did a 26 week 4 day us and the tech said they were about the same i felt a little relieved that at least it wasnt worse..well today i get a call frm a high risk office scheduling an us because my dr had sent over a referall and i freaked because no one frm my drs office called nd discussed anything with me. I called the nurse at my drs office and she apologized nd said they just wanted me to follow up since it has increased from 5.5mm to 9mm now. I was furious that the tech told me it was still the same as before. I am just extremely worried!! Has anyone had something like this happen or is going through it? ;(
