Is there any way to get a perscription for birth control without my parents knowing?

There are several routes. You can speak to your family doctor who has "client confidentiality".. that is he can't tell information to your parents without your permission.

The second route is to go to your local "Family Planning Center". Here is a site with phone numbers of local centers.

If you are having sex out of marriage, you need to think about using condoms also even if you are taking birth control to help prevent the risk of STD's.

Abstinence really is the best route though.

as sher said abstinance is the only 100% way of prenventing pregnancy as well as STD. and remember that even though you use both together (the pill and condoms) you are not completely safe from catching anything or becoming pregnant.

My husband has MANY "friends" in the military who thought they were being safe but ended up with a STD anyway! It is just my opinion but if you aren't old enough to discuss it with your parents and are trying to hide it then maybe you shouldn't take on the responsibility that having sex brings with it.

BE CAREFUL- and just always remember that everytime you have sex you could be looking at a LIFETIME of new problems by way of either a child you can't provide for or a disease that may or maynot take your life.

I totally agree with the abstinence suggestion being the only safe way for birth control. I know it sounds old fashioned and is most likely not the answer you were looking for but this is a decision that can and most likely will affect you the rest of your life in one way or another. If this is the first time don’t do it just for the sake of doing it, or cause your partner pushes you to do it cause they say they love you or cause you really like them a lot. Sex now days is one of the deadliest weapons out there now due to all of the STD's. Someone who you would not even suspect to have one could be a carrier. Play it safe and do what your heart tells you not your emotions or pressure from another. Just like Shawn's husband I too some people who thought they were playing it safe with "protected" sex, (using a condom) some got off easy with being pregnant (not saying it lighthearted either) others have mementoes to carry with them for the rest of their lives (STD). Not to say that being pregnant is easy cause it's not but it was the lesser of the two. Sorry for the soapbox speech but I hope this helps.

This depends on a number of things, mostly what the age of consent is in your state. Some states require that a minor get her parents' permission before going on birth control. Some do not. But if you are not a minor, your parents cannot prohibit you from going on birth control, no matter what the state is. You are seventeen, right? You should check the law in your state.
And if you are in a state that does not require parental permission, you need only visit a doctor or Planned Parenthood clinic. Everything is covered under doctor-patient privilege.
Here is a listing of locations in Kansas and Missouri.

That said, I must add to the lecture others have given. It is true that abstinence is really the only 100% way to be safe (and that means NO sex: no oral, no anal, no naked fondling, nada!). However, if you truly feel that you are ready for the responsibility of sex and willing to take responsibility for the potential consequences of sex, then you must be sure that you are as protected as you possibly can be.
Birth control is very effective against pregnancy but it does NOTHING for STDs. Condoms are best for that, but they must be used properly and every time. You MUST be protected EVERY TIME. Birth control is not enough.
