They said it takes 20 mins., and I can't imagine 20 mins. of that kind of pain again!
The whole procedure takes 20 mins--including 10mins of chatting with the doctor, 5 mins after the insertion of having a glass of water and getting dressed... You spend 5 mins in the stirrups, of which 4.5 mins is "normal" gyn procedure. The painful stuff takes a couple of seconds. The first instance of pain is when she inserts a sond of some kind, probably 2 sec, and then when she inserts the coil, another 2 secs. I'd say that if I was able to handle it, with my non-existant tolerance for pain AND never having given birth, anybody should be able to. The pain I was referring to lasts for a total of about 4 secs.
Also, if you have given birth your uterine opening will be a lot bigger than if you haven't, she looked at mine and said, "oh my, that's tight"... She said that for women who've given birth it's usually just mild discomfort, comparable to a standard gyn exam.
Oh, and I'm completely fine today. The period-like pain went away in 4 hours, enough that we went out to eat to celebrate me getting rid of hormonal birth control. I'm still taking it easy today, just in case. I really don't want to do anything that might aggravate my insides and instigate expulsion (although I'm not sure if that's even plausible).
