So I have a question, has anyone used the nuva ring?

Kirsten • Im Kirsten, & I'm a mommy to Jazmyne
I'm 30 weeks pregnant and my dr is already offering me birth control, and my SO and I were talking about it and he offered me the nuva ring because I'd talked about it before, but I want to know if anyone has used it and what the side effects were? 
Help please. Thanks. ☺️
