Growth ultrasound

Hey ladies, I’m wondering if any of you had similar experiences!

I’m 30+4 weeks pregnant, I’m measuring 34 weeks, and today I had a growth ultrasound to see the exact measurements. Is it just because I have a lot of fluid? This is what we were trying to figure out.

So all the measurements looks good I guess,, ranging from 28 weeks to 32 weeks. Except for one.. her head circumference.. a whopping 36 weeks and 3 days!!

Has anyone experienced this and had their child come out with a normal size head? Did they grow into it?? Haha I’m so worried!
