I hate triggers so bad

I have to get an ultrasound on my ovaries at the beginning of December and they called me today to tell me what I need to do to prepare for it and the second they asked if I’ve ever had a pelvic ultrasound my heart sank… I know it’s a simple medical procedure and it doesn’t hurt but it’s one of my triggers due to abuse I went through as a kid and while I know it’s important I do this ultrasound I’m so nervous and dreading it 😥
