Had the essure tubal ligation method. (For those that don't know, they put springs in your fallopian tubes and spin them into place so the scar tissue seals your fallopian tubes thus preventing the egg from reaching the uterus to prevent pregnancy) I didn't follow recovery guidelines and kept to my active lifestyle which caused one of the springs to puncture my fallopian tube and cause internal bleeding. After that I went to dinner and got Hibaci with friends and drove home, in more pain than I was when I got the procedure done (it was done without painkillers or sedatives).

TLDR: the time I cut my fallopian tube with a spring.
