Emergency room visit vent

Went to the emergency room yesterday for cramping. I called the nurses line before I went and they encouraged me to go since it has been pretty consistent and been going on for a while now. Everyone was so sweet when I got there and understanding. They did a urine sample, blood work and then 2 ultrasounds. The lady who did the ultrasound on me was so awful. She came in and already seemed annoyed that I was even there. When I explained everything to her she rolled her eyes at me and in the 45 min it took her to do both ultrasounds she didn't say a word to me except to complain about how uncomfortable she was and kept sighing. I felt bad for even coming in. This is my second pregnancy and never experienced any cramping with my first one so I was just really worried and wanted to make sure everything was okay. I am a little over 6 weeks now and have not told many people about my pregnancy besides my husband and some coworkers so I just really needed to vent.
