Hello, thanks for reading this.. I am 19 years old and am nearing the end of my freshman year in college. I started my period when I was nearing the end of 7th grade, meaning that I've been having it for almost 5 years. Well, last summer, my regular periods stopped. I had one in July and then did not have one again until November, and only had one because I went to my gyno who prescribed me a "self-starter" medicine, basically a pill with the opposite idea of birth control. I took the pills and my period started two days later and lasted less than a week. After that, I decided that maybe I should wait out my next period and see if it comes on its own. Well, it came, a month and a half later. That was in the middle of December. Now, it's March, and I haven't had my period since Christmas. My gyno didn't seem concerned at all when I told her that I hadn't been having them, and she owed it to "stress" for their absence. I am honestly not that stressed, and I would really like to know why I haven't been seeing any red for several months.. Any thoughts?
