I've had them before ... the first time was incredibly painful and it was determined that my cervix was stenosed. This was a test to be done before my ablation. She just couldn't get in, so I was going to be scheduled for 2 hysteroscopies, 1 to do the biopsy and the second to do my ablation. Well, about 2 weeks passed and I was in for my pre op appointment, and my OBGYN says "your cervix looks really soft ... do you want to see if I can get in this time? If I can, we only need to do one hysteroscopy". Of course I said yes. She slid right in easily and the only pain I had was just the part where she snipped and sucked the sample. Just 2 days ago I had a saline ultrasound and again, my cervix was not cooperating, and the pain was beyond horrible. Here's my question ... I've since read that your cervix changes throughout your cycle. I was close to ovulation when she was able to slip in and just a few days past my flow when she couldn't. Why can't they do these procedures when the cervix is softer? I think the pain comes from a tighter cervix and never the actual tissue sampling. Might be something to ask if you need this test done.
