The only additional advice I would have would be have a plan if there would be an oops. No birth control is not 100% sadly.
I have a child conceived while on the pill. Even permanent forms of birth control can fail. I had to have emergency surgery on Sat at 3 am. I got pregnant after my Essure implant (similar to tubal ligation) failed and resulted in an ectopic pregnancy. It was my boyfriends baby not my husbands. It failed after 6 YEARS of no problems.
My doctor says he has seen tubals and vasectomies fail after even 10 years of no problems.
