Well, I’m 17, and the first signs I had were tiredness and implantation bleeding, though I didn’t realize what the later was at the time. Soon after I had morning sickness, and I became VERY sensitive to smells. BUT, it’s important to realize that everyone’s pregnancy symptoms are different, and the only sure way to know is to get a test (blood tests from the doctor are the most accurate). Also, don’t freak out tooo bad until you are really sure you are pregnant (being nervous could cause you to create false symptoms). Hope everything turns out for the best either way!! ~~Jessica
