Is it a bad idea to rely only on a hormonal form of birth control?

I recently found out that I'm allergic to condoms. I'm busy to be married, my fiance and I are both completely disease free and we are monogamous to each other. I use Nuvaring. Is it a discouraging idea to rely with the sole purpose on that method? Do other people? I don't really own any close girlfriends to talk to more or less this.

Using back up protection is without a doubt always better. You can other change to a different method of hindmost up such as spermicides creams etc. Just make sure you chat with your doctor previously using any other for other than a condom. But, it's not "bad". I appreciate you not wanting to clutch risk and respect that 100%.
