BC for 5 years now TTC

Lauren • Just welcomed our sweet little girl into the world on March 22nd! I am the proud mother of 2 little boys, 6 and 3. My husband and I have been married almost a year but have known each other for close to 21 years!
I have a 5 year old son and a 2 year old step son. My husband and I just recently, 2 months ago, stopped any form of birth control. I've been on Nuvaring for 5 years. We are TTC but I'm anxious that it won't happen soon. Any advice on how to calm down about it? Also, how long after BC before you can conceive?
