really if you dont know this stuff you should not be having sex,every time you have sex even with contraception there is a chance of pregnancy,dont have sex if you dont want a baby..its as simple as that.
im 19, my boyfriend and i use condom but sometimes we dont, it's not the same, i want to start taking pills but he doesnt want because he says it might get me steril
use condoms all the time or get some type of contraception...if you visit your doctor he/she will give you lots of information.
there are many forms of birth control on the market now,get informed,both of you and make an informed decision.
there are millions of women who take the pill every day for years and have not become sterile....
however,if you continue playing russain roulette with his spearm and your overies you going to hit the jack pot and you will both be parents...
i strongly suggest to consider a visit and get informed.
i also suggest you re educate yourselves on the reproduction system and sex education.
i am not saying that to be smart with you,only to suggest you both realise the implications of unprotected sex.
there is a mountain of information on the internet,also health clinics and well women centres if there in your area..
when you find out these things you will be more in control of your body and how it works,then you and your boyfriend can high five each other for being responsibility and mature..
where are you? why not planned parenthood? they can help you even if you don't have insurance. or, even better, as suggested before, don't have sex. you think you can't afford contraception...try affording raising a child. bc is a whole lot cheaper than diapers, bottles, baby furniture, car seat, stroller, baby dr visits, not to mention your own pre-natal care, then there's maternity clothes, and baby clothes, formula, baby food, baby toys. bet bc isn't looking so expensive anymore compared to the alternative.
