Why don't people who don't want to get pregnant use a back-up Birth Control?

In this day and age there's no excuse for having an unecessary pregnancy... There's so many method's of BC it's ridiculous.. I'm tired of ppl. "Oh my bf pulled out could I be pregnant..?" Or "we didn't use a condom, could I be pregnant?" just because you are on the pill doesn't mean that you can't get pregnant, especially if you aren't taking it properly if you are confused about your choice of BC you should be using a back-up birth control method (condom,VCF,Spermicide etc...) Also, if you have more than one sexual partner you also should be concerned with STD's that the "pill" doesn't protect against.. He should be wearing a condom and if he won't because they are "uncomfortable" so is peeing fire and an STD... Please ppl. be more responsible with yourselves....

* Someone asked "Why should I care" I do care and so should everyone that works, who do you think pays into the welfare system.. DUH....!!!!

Because people think, "It won't happen to me." Not just regarding sex. They think this regarding motor vehicle accidents, smoking, drug use, whatever! Because it hasn't happened to them yet, it won't happen at all, right? Because they've been lucky so far. Or they'll worry about it later if it does happen.
