I'm 17 years old, and my boyfriend and I had unprotected sex about one week ago and many more times after that. I didn't get my period yet, and I was suppose to have it about August 1st or 2nd. I have nausea, cramps, fatigue, and I've been eating more. I definitely FEEL pregnant but the test came back negative. Please don't tell me I need to tell my parents, I have to know before I tell them. Do you think I should wait and take another test? I'm not sure what to do.
