Call planned parenthood. They are all over the place and hopefully there is one in your area. They probably wont charge you anything for a test. I dont know your situation, but they dont have to notify your parents to do a test. Tell them your symptoms. They should be able to help you. If you dont have access to planned parenthood, call your health department, they have a low or no cost clinic you can go to. How long has it been since your last period? Is there a possibility you may be pregnant? The only thing that is foolproof is having no sex at all. Even on birthcontrol, it still may be possible to get pregnant. If you are pregnant, the line you may be talking about is from your navel to your pelvis. That happens to a lot of women. Its nothing to worry about. But you still need to see a doc. Im a mother of 3 and thats what I would want my 15 year old daughter to do even if she didnt tell me. Lots and lots of luck to you!!!
