So I recently got a new form of birth control it's called Nora-B. If any of you guys have used this before could you tell me your side effects? And also how long did you have it in your system before unprotected sex. I'm married with 2 kids. 9 and 2 year olds. I decided to go back to school for dental assistIng and getting pregnant right now wouldn't be the worse thing but it's not the perfect timing either. I've only had the mirena as a form of BirthControl in my entire life so I have no idea how pills work. I have been taking it everyday at the same time for 9 days! My doctor wasnt as informative as I wanted.
