I shouldn't have my period for about another week, but I keep spotting and I feel like I should have my period. I had sex two weeks ago, but it was protected.... does this mean I'm pregnant? I'm really worried cause I turn 17 yesterday and my parents will be so mad if I am. What do I do? and How do I know? Is it just because my body is a little out of wack? Or could I seriously be prego?
