"Ultrasound scan"

I went for my scan on 29 September and it was an horrible experience. The lady who did my scan was so rude. She told me to undress myself in front of her which was a bit awkward to me. I asked her few questions before scan as I was bit nervous but she replied so rudely and was literally shouting on me. The transvaginal scans are bit uncomfortable so I think they should be little bit patient.
