The best of your choice of birth control is abstinence. I know that most teens do not listen to this advice and I was one of them. You can do deep research on the internet to get the best birth control solution.
Your other birth control options where you might start to get confused. I realize that some people are determined to have love relations and talk about abstinence is not going to help keep them from getting pregnant. It is not important what kind of birth control you use; what is important is that you use it.
If they tell you that you will not get pregnant if you have unprotected love relation, you should know they're lying to you, probably just to get you to do it.
