I find that if you are going to have sex...you have to be open and mature about sex. I was 17 when I got pregnant with my first child because i was told the "pull out" method works great!! HA! It doesn't. I am proof it doesn't. I am a perfect example of listening to what others said, and being SO naive! So I tried the ovulation thing cause I was told it worked...nope...that's how I have my second daughter. I think the best thing to do (which is what I should have done) is go to the doc. and get on birth control. I think it makes your sex life easier because the last thing on your mind is getting pregnant. Works great for me now. I do think it is important to be CAREFUL when you are having unprotected sex, AIDS and STD's are another big risk you have to worry about, and we all know that birth control will not protect you from that.
Be careful please!!
