The jist of the story is a couple days ago my fwb and I were messing around then I decided to penetrate her a couple of time( No protection), but didn't finish. She is on birth Control also by the way. So I am not sure if she is because her period does not start till about end of the month. I do not think she is worried at all, but I am pretty worried :/

She could be pregnant, no form of birth control is 100 percent. Now you have to wait and see is she is pregnant

What sort of birth control is she using? As Fr_Chuck said, no form offers 100% protection, but if she has been using birth control pills, for example, and using them correctly, odds are low she will become pregnant. Add to that the fact that you didn't ejaculate decreases the odds even more.

Certainly possible, as anytime you have sex pregnancy is possible, just not probable given the situation. Easier said than done, but try not to worry. To help ease some worry in the future, consider using two forms of birth control.

She is using pills. I know they are like 95-97%? I guess if she is pregnant I will have to step up and balance college and her.

Yes, you would. It would take work and effort, but it certainly can be done.

If you don't want any worry, stop having sex. If that isn't a possibility, consider using condoms along with the pill to lower the risk even more. Good luck!
