Well...

We had sex and I ejaculated inside of her. She is on a pill. What are the chances of her getting pregnant? I'm losing my mind right now and I am scared as hell.

We are both not ready to become parents and pregnancy is the last thing that we want.
Help?

Oh, I tought it might be important; two months ago she had forgotten to take a pill and skipped a whole pack of pills. She started the new pack of pills the next month . After this little acciddent she is taking the pill religiously everyday at the same time. Does it change anything?

Should she get a Plan B? What should I do?
