Actually, I just remembered what the real lay out was. Again, this was from years ago, and today is the first time I actually thought about it. I told the story incorrectly.
She had been using birth control and had ran out, but she didn't mention this before we had sex(not good). The next day she went to get the morning after pill to make sure(i.e. emergency contraception). She didn't keep them on deck.
Either way, she should've told me but she didn't. Then she made some jokes about getting pregnant, which shook me up. She got the morning after pill and all was taken care of. I learned from the situation and became much more cognizant in future encounters.
Peace
