Start using condoms from now on.

From Create Your Own Story

That was too close of a call and you don’t want to take the risk of getting Karen pregnant or catching a STI. Condoms work great if you use them every single time, and there is only a 3% chance of getting pregnant, but in most typical teenage couples who are only using condoms 14% of them get pregnant in the first year. While 14% doesn’t sound that big, but you don’t want Karen to end up in that group or even the 3% group because it can happen to anybody. In addition to using a condom you think it might be good to talk to Karen about getting her started on birth control.

In many states like Illinois you don’t need a parent’s permission to go to a clinic or doctor to get a prescription for birth control. Many community clinics and planned parenthood offer birth control at a reduced price. With the many different kinds of birth control available there is something for everyone's preferences, and if Karen tries one and it doesn’t work for her, tell her not to give up and to try a different kind!
