3rd Trimester Ultrasound...

Brittany • FTM, impatiently waiting on a baby girl!
So my doctors office has been super stingy about ultrasounds, I have had 2. My last ultrasound was my anatomy scan at 20 weeks (I'm at 33 currently) and at that scan t was very short and quick and the tech was rude and barely gave me any info. I asked if I was going to be getting another ultrasound and my midwife said it was unnecessary.
Do you think it's reasonable of me to ask for another ultrasound to be scheduled?
