I'm 26 years old, otherwise healthy, and usually have quite normal periods. I have skipped a month or so before, but I have now been late for 64 days. My last real period was January 3rd, I then spotted brown blood (old blood?) on January 30th. The only change in my life in the last few months has been weight loss. I've been eating a lot healthier and I've lost about 8-10 pounds over that time. I also run around a lot at work and don't often have a chance to eat a lot, and often am under some stress. I'm just a little worried about how long its been. Over the last couple weeks though I thought I've been having signs of PMS, especially hormonal breakouts on the right side of my jawline and chin, which I usually get a couple weeks before my period. I hadn't had this happen in a couple months. I'm hoping now it will show up within a week, but I'm stressing out a bit now. Should I be worried?
