Ok, so don't get me wrong It is uncomfortable and you definitely feel something. But is by no means jumping off the table painful. I had a PA doing the test on me with the doctors supervision. I was even told that they had to push the cannula a little harder to get it into my small cervix. I would definitely recommend taking Advil or some sort of Ibuprofen about an hour before. Also afterwards I was a liiiiiittle bit crampy but was still fully able to go to work that night.
