Take a test: Take a home pregnancy test, you can obtain them at supermarket or drugstore. If the test is positive, it's possible you're miscarrying. If the test is negative, it's likely your period. I see you are 14 years of age. Think about making an appointment at a local clinic to obtain birth control if you're not pregnant, 2 methods is best, for instance, condoms with pills to protect from stds too.
