Expert answer:
You are already 17 years old should have thought of this, in fact before even having the first relationship. Contraceptive pills and condoms (condoms) are the most common ways to prevent pregnancy, ideally you should seek a doctor who will prescribe you a contraceptive pill. Even so, use condoms, because besides protecting you from pregnancy, it also protects you from sexually transmitted diseases. There are other contraceptive methods (injection, implant, IUD, patch ... and sexual abstinence ...)
