to be honest i think if you wanted a more sexual relationshjip with your b/f a pill of some kind would be good, i was on the pilll but recently came off it and now i am pregnant but i wouldnt chane it for the world, i am also only 17 and had to quit college as i am now pregnant and a move to a new country.
but i think i pill could suit you if you wanted more of a sexual relationship, you can always find a pill that suits you personally as there are many, and yes your hormone could change a bit but once your body gets use to it your hormones should sort themselves out i changed my pill 3 times before i found the right one for me.
its just an idea for the future, but i would use a condom too
and thats fine you dont need to thank me thats what this site is for after all!!
if you are still stressing about it do get a home test that will sort out any ifs and whats, and if you cant afford one you can always go and see your doctor and they should do a test, if you used a condom and didnt "finish" then i dont thinks there much of a chance if you had not used a condom it would be different but i dont think you should have a problem would be worth getting a test though hun
what has your b/f said about it?
