What are natural ways for a woman to not get pregnant?me and my future husband don't want kids right now. what would be the healthiest thing to do?

Condoms consistently: The only way to totally prevent pregnancy is to avoid genital-genital contact entirely, and many unmarried couples find mutual masturbation OK at this stage in their relationship. Next would be barrier protection with condoms: quite reliable if used consistently & Plan B is available in a mishap. Most successful is BC with BCP, patch or injection. Withdrawal and sex only during menses is not safe

Abstinence. But why?: Abstaining from intercourse is the only way to be certain to avoid pregnancy without a form of birth control. That said, if you know you want children later, and still want to be able to enjoy sex other then oral or digital/manual stimulation, why not consider a durable method like a copper IUD? That's as close to natural contraception as you will get. Talk to GYN about your options.
