Buy a Pregnancy test at a Pharmacy or you can go to a Doctor, they are not allowed to tell your parents. In most states there is Planned Parenthood, they charge according to ability to pay and they help to test for pregnancy, they also respect your privacy. Worry can cause the signs you are showing. Also, it is possible to have a period and be pregnant. The test will tell you for sure.
