If you are at University, there ARE people who care, and who will help you cope if, that is, it turns out that you are right about this suspected pregnancy. Chances are that you are worrying for nothing and the more you worry, the later your period will be, which makes you worry more, and so on. In fact, you may by now have found out that you were wrong and it was just a guilty conscience troubling you!
First move - get it confirmed. Go to the college doctor for tests and advice.
If you were wrong - stop panicking and make up your mind to use more common sense next time you have a one-night stand. Even better, don't have a one-night stand.
If it is true - second move - discuss things with your counsellor. No-one here can tell you what to do without knowing you and speaking face-to-face. This is not the right place to go for advice.
Third move - either accept that you will become a single parent and start planning how to support a child - not just a baby, but a child, who will grow into a person, and be your responsibilty for at least the next eighteen years - or accept that you are going to ask for the pregnancy to be ended, with all the heartache that will bring.
Fourth move - when you know what YOU think and feel, consider whether or not to tell the baby's father. Because that is what he is, not just a one-night stand. He is probably as young and unready as you are, but he has rights as well as duties. If this situation becomes reality, it is not just a soap opera or a fantasy, it is a life, created by two people. Get professional advice to help you decide your future.
I'll say it again, this is not the place to get counselling, go to someone with training and experience in dealing with the problem.
