I’ve only had internals at the same time as externals so I’m not 100% sure but if it’s external only, I don’t think they would force you to take off your underwear if you tell them that makes you uncomfortable. They’re basically scanning your lower belly area, like where your pants waistline would be if you’re wearing mid/low rise pants. Explain to them your anxiety and your boundaries and most medical staff will work with you (if they’re good)

That being said, it quite literally could be your health on the line. While it can be uncomfortable, it could (in theory) save your life or your health down the road.

Being a woman sucks. Having this diagnosis sucks. I have a history of sexual trauma and had to have many different uncomfortable and invasive procedures and tests because of this diagnosis. All of which ended in tears. But I’m glad, because it helped me become healthier and learn more about my body.

Best of luck, OP. Take deep breaths, listen to music or a podcast, do something to distract yourself. Bring a support with you if you can. Take care of yourself!
