I've had unprotected sex with my bf many times but now my period is 15 days late. I've had naseoua and I've only actually thrown up once. I've had a couple other small symptoms like cramps and boobs hurting. I haven't taken a test yet but now that I've thrown up I feel like I am. I am 15 and need advice and I can not tell my parents only as a last resort. Should I go to the doctor and see? I need advice asap!!!!!! Please help!!!!!!
