So I want my tubes tied

When I tell you this pregnancy was a pure accident I mean it. Never in my life have I wanted to have children, I just wanted to adopt. Figured there are plenty of children that need loving homes without having to add mine to the mix.

Of course, I'm in love with this baby (after a brief talk with my mama, decided to keep her) but I'm 100% positive that she's going to be my last.

I'm 19, and realize I'm likely to be denied for a while because of my age, which I'm okay with. So can anyone tell me around what age they had their tubes tied and just more information about the procedure/recovery time?
