My advice, learn how to spell. Honestly, devote more time to studying and less to boys. It will help you immensely as you get older. Also, understand how our menstrual cycle works. Chances are good you've had several health classes by this point. If not, go to WebMD or something and learn exactly how everything works. Finally, take a pregnancy test to see if you're pregnant. I don't mean to be rude, but seriously. This is the FIRST thing you do when you think you're pregnant. I don't understand why so many people come on here to ask if they're pregnant based on some symptoms alone. Experiencing pregnancy symptoms does not mean you are pregnant. It is very easy for stress or a million other factors to effect your hormones. Slight hormonal changes cause a lot of different "symptoms" in your body. And, simply thining you are pregnant is enough for someone to start thinking they are having pregnancy symptoms (which not every woman experiences, and don't usually start until 6 weeks into the pregnancy anyway).
