Natural methods of birth control include fertility awareness-based methods, diaphragm, condoms, and the copper IUD or Paragard.
The hormonal IUD is different from all other types of hormonal birth control in that it does permit some ovulation and natural cycling.
Other benefits of the hormonal IUD are that it dramatically decreases menstrual flow and can relieve symptoms of endometriosis.
There are some downsides to an IUD.
The copper IUD or coil (ParaGard) is one of the few non-hormonal methods of birth control. Its main advantage over hormonal methods is that it contains no contraceptive drugs and permits natural, ovulatory cycles.
It’s not perfect but it’s certainly worth considering.
