How effective is bisalp?

I had a bilateral salpingectomy (bisalp), but I still find myself worrying about getting pregnant. I know it’s supposed to be one of the most effective forms of permanent birth control, but my anxiety keeps making me wonder about the “what ifs.”

If my husband finishes inside me, am I still safe from pregnancy? Do any of you with a bisalp still let your partner finish inside without using any other protection?

I’d really appreciate hearing from people who’ve had a bisalp or from anyone who knows more about how effective it really is. I could use some reassurance.

Thank you all!
