a lot of young girls think they could be pregnant because they had sex, which is a possibility, but they seem to freak out and think they are pregnant only because of the fact that they had sex. until you have a legitament concern, play it cool, dont freak out. if you have a late period, an unusually light period, or other strange symptoms, then it is a cause for concern. if you do have some of these symptoms, is there any way you can get your hands on a pregnancy test? that might be easier than going to a clinic.
Good Luck! Keep me posted!
