Hi, I am 19 years old and I am currently 6 days late for my period and I dont know why. I havent had any sex for about 6 months, and had my periods regularly ever since I started getting them when I was 13. However, I did just move back to college, came back from a trip for the golf team, my diet has changed (b/c of the dining hall options) and now I'm worrying about all of this. Could my late period be because my body is slowly adjusting to all these changes? Or is there a chance that I'm pregnant?
