I haven't had a period in a very long time... I'm talking almost a year now that I realize it. I'm just so busy and stressed with school 24/7 I didn't even realize it. I've had sex a few times just this past December and every time was with a condom. I don't understand what's happening or why it's happening. Has anyone else had this happen to them? What was the outcome? I mean sure I could go to the doctor's, but it's expensive and unfortunately I'm a poor college student. Help?
