You are at risk: If you are healthy, have a regular menstrual cycle and had unprotected sexo-genital intercourse with a healthy man about your time of ovulation, you are at risks of getting pregnant. Be safe. Ask a knowledgeable gyn who cares for adolescents for an intrauterine device (IUD) or a subdermal implant and use condoms too. These are the most effective Long-Acting-Reversible-Contraceptives.
