Human: I'm looking for a natural alternative to birth control. Do you have any ideas? Assistant: 
I’m not sure what you mean by “natural”. Birth control is a method of preventing pregnancy, and there are many different types of birth control that work differently. Some methods use hormones, some use physical barriers, some use both. You can find more information on the topic at https://www.plannedparenthood.org/health-topics/birth-control/.
