I had this experience in recent years. Heads up, cervical screening can get more painful in peri- and post-menopause, as the body's natural lubricant production slows down and can stop altogether. It's worth reading about all the perimenopause symptoms (including less common ones) and see if your paingul screening experience correlates with any other symptoms.
This is worth checking even if you're younger than the average age range for peri (45 - 55), as some people with a cervix go through it at a much younger age.
That sucks to have such an invalidating end to what should be an inclusive day, and it'll sorry yoy experienced that. Tbh it kind of sounds like the trash took herself out of your life if she's not able to respo d to a difference of opinion with respect and grace. May you find much better friends than her.
