Pelvic MRI today

Wish me luck! Doing one to see what type of ovarian cyst I have, and to check the pelvis for endo adhesions. It's been years since I had an MRI and I'm doing it with contrast. A little nervous about that. I've had contrast before but can't remember how I reacted.. I think I was fine otherwise I probably would have remembered. I'm mainly concerned ab nausea. I was ordered to fast for 4 hours, so my tummy is already grumbly! 😕
