I'm 23 the past couple of weeks I haven't been able to sleep at night. I just don't want to eat anything and when I do I get slightly nauseous. I've been having terrible headaches I at first thought it was my eyes cause I do have bad eyes but its been higher up in the forehead. Normally I have severe cramps right before my period but not this month.  I haven't had my period yet but I'm going to take a pregnancy test in the morning. Is it possible I'm pregnant?
