Has anyone used a Female condom?

Ive been very worried about getting pregnant lately im on the nuva ring an have been for 7 years alomg with frequent sex ive had no peoblems with it and use it correctly. I have two questions. Question 1 is how do you guys feel about the nuva i know with every contraption you can still get pregnant but i always feel like im going to be that 1 in 100 person lol. Question 2 has anyone used a female condom and also birth control i feel like i want to be extra careful just because i dont want pregnant male condoms will more then likely be out of the question because "he cant feel anything"
