Alright so I am a 17 year old girl, still in high school. I am very scared right now because my body is going through some things and I can't quite figure out whether or not this is due to a pregnancy or what. I received my period - thank god! - but then less than 2 weeks later, it came back. I didn't think much of it until my aunt asked if I had been having sex. The same exact thing happened to her when she got pregnant. I'm trying to disregard this but I recently just started experiencing what may be "morning sickness". I can't really keep food down. My food intake has gone up - but maybe that is just in my head. I really don't know what to think...help?!

P.S. I will take a test, but I'm having trouble getting one without my parents knowing.
