Cried at pelvic (and surprise transvaginal) ultrasound. Feeling so embarassed.

Today I (23F) had my first pelvic ultrasound (to investigate the cause of my Oligomenorrhea) and I followed the instructions exactly as they said : drink 750ml of water an hour and a half before. I got there and already I was in pain from holding in so much pee.

It was 15 minutes past my appointment time and I couldn't take it any longer so I asked a secretary if they knew how much longer it was gonna be because I was really uncomfortable and I was literally trying to hold back my tears and my voice was so shaky. She went to check and moments later I was called in.

The ultrasound-er was a young woman and she was so cold and short with me. When I laid down I started getting back pain because of the pee and I was crying and she said I drank too much water (but I literally drank the amount they asked).

And then she surprised me with a transvaginal ultrasound that I had no idea I was supposed to have since it wasn't marked on the paper. I asked the ultrasound lady why and she said they usually come together because you can't always see everything in a pelvic ultrasound.

So I was just there crying, the doctor had no empathy or kindness and I feel like such a baby for crying. I'm so embarassed. Please tell me it's not just me? :(
