Tubal Ligation after first pregnancy

I want it done.

I told my OB at 33 weeks that I wanted it.

She said I didn't sound confident enough to have it done, and therefore she wouldn't perform it.

I do not want to be pregnant again. Don't get me wrong I cannot wait to have my baby, but I do NOT want to be pregnant again.

The emotional and mental wear my body has taken on is insane to me. I suffer from mental illness and I do not want to do this again. My SO said he would have a vasectomy, but then he changed his mind. He isn't 100% sure about an elective procedure and I am.

She backed herself up by telling me I would still need to continue taking medication due to the risk of ectopic pregnancy and I have crazy hormone issues. I'm willing to do that though.

Should I speak to my family physician about having this procedure done or should I keep trying to talk to her?
