You're pregnant.
It seems from your frowny face that you didn't want to get pregnant. You know very well that having unprotected sex is an invitation to get pregnant. And you did it for 4 days straight? Why?
You know what you have to do if you don't want this baby. If you do it, do it soon. If you can't decide yet, at least take pregnancy vitamins for the folic acid the baby needs in order to prevent spina bifida and some cleft palates (this is so important in the first weeks of pregnancy.) And don't drink alcohol during your first trimester. If you end up carrying to term, you will have given this baby a chance for a healthy beginning.
If you can't take care of a baby and can't deal with an abortion, give the baby up for adoption.
If you really aren't pregnant (which will be a small miracle), learn from this "scare" and stop having unprotected sex.
