So this is not an answer to your question exactly, but have you considered a vasectomy for hubby? I slways planned on tubal ligation post kiddos as well, but both of our doctors said that a vasectomy is much safer and lower risk than a tubal ligation. We did our own research and it tracked with that assertion. So our game plan was if I needed an emergency C-section, I would go ahead with a tubal ligation (no sence in both of us having surgery) and otherwise he was going to have a vasectomy. Some people have asked him why he would volunteer for this and his response - my wife has had to deal with 2 pregnancys and 2 births, it was my turn to step up.
He did it 3 weeks post delivery and besides some local swellimg that resolved quickly has had no complications. It is an out patient procedure, very quick and he didn't even need all the prescribed pain meds.
So, just something to think about.
Also, I am sorry you have to defend your choice to be done having children. This is one area in which people seem to think it is ok to treat you like you are not capable of rational thought. I can't tell you how many people have told me we would change our minds about wanting more than 2 children. I would have told you when I was 13 years old that no one would ever convence me to have more than 2 children and I still feel the same way. Children are a blessing and family planning is a healthy, mature way to make sure you can take good care of those children you have blessed with - good for you!!!
Whatever you decide to do, I hope it goes well!!!!!
