Does contraception alone prevent pregnancy?

I will begin to have a sex life with my new boyfriend, we did tests and we do not have diseases, is it only the contraceptive prevents pregnancy? I and he do not want to use condoms just the contraceptive!
Expert answer:

Yes, stay calm, the contraceptives taken correctly are very safe and effective, I will give a personal example: my wife used for only seven years contraceptive until she stopped to get pregnant with our first child and in the seven years she took the pill , we never had problems, of course she was very careful with the schedule.
