If you don't know by now how a woman can get pregnant, then you aren't old enough to drink or have sex. You did not have sex, so you are not pregnant. I suggest getting educated about sexual relationships.
Hi Ashley,
You mentioned that you had some drinks, some times we can forget a few things that we have done under the influence of alcohol. For your peace of mind I will go to the grocery store and buy a pregnancy test. If you are 5 days pregnant by now the test must be very positive. If it is not you should consult your doctor, since is not normal to miss a period with no reason, if, you are a healthy women.
I hope it all ends well for you. And please do not take any rushed decisions at this time, think the things through before you make any decisions. There is always many more options than people may want you to believe you have.

If you didn't have sex then your not pregnant.
