See details: Abstinence or birth control (condoms, oral contraceptives, iud). Other methods such as pulling out before ejaculation are far from foolproof.

Big picture..: There are primarily two kinds of birth control. Hormones and barriers. Hormones include pills, implants, and injections. Barriers include condoms, diaphragms, iuds and more. What's right for you two as a couple depends on how you feel about the pros and cons of each method. You should be able to find a good overview of the options via an online search, but then discuss it further with her doctor.

Family: Planning can be done reliably. Male condom use is mostly successful. Female birth control pillshave some hazard of blood clotting in some. If you opt to never have children vasectomy for men, or the more invasive fallopian tube tying fir women.
