ER visits goes wrong

I can't get over the fact how last month I went to the ER cause of pelvic pain, it turned out to do test on my abdominal cause the NP thought I had appendicitis. I'm like I didn't come in with abdominal pain she said let's do an MRI just in case. I was so nervous, they gave me IV and meds I didn't request to relax before the MRI, they put me through so much cause I was 16 weeks pregnant now I'm 20 weeks. I got blood work done, a Pap smear, ultrasound which I was happy to see my baby and but not happy with doing the  MRI at 3am. I loved the NP that took care of me she was a sweet heart but I was just frighten to death. I still have scars from the IV causing a reaction which left a bruise which reminds me of that horrible day. I been out of work ever since because it was my second time going through my shift, and they thought it would be good that I stay out for a while from work. I don't think I should return now especially with my baby laying low in my cervix. I work in the same hospital that took care of me. -,- different floor.
