Natural Birth Control

Ladies! my boyfriend and I have decided to start doing natural birth control. (we've been dating 2 years, marriage is definitely in the future so if there's an accidental pregnancy we would be fine) we've started using more holistic medicines and are ditching certain medications. we've been feeling great and both a lot healthier. I've been off the pill for about 6 months now but have only been tracking myself for about a month now. do you ladies have any tips and tricks? or any stories or experiences with natural BC?
