So in September I got my period two weeks early, and it was a lot lighter than normal, without any of my typical PMS symptoms except maybe very minor cramps - so minor I barely even noticed, and only on the first day. My period was on the 29th the month before, and then in October I got it on the 25th and that period was normal in length, PMS symptoms, etc. (which I thought that maybe was because the one I had on the 17th was just weird, and my cycle went back to normal after that). But then today (the 17th of November) I noticed very minor cramps again, which I didn't really think much of for some reason, and ovulation ended a few days prior - maybe 5 or 6 days ago at the most? But then I noticed dark brown discharge, exactly the same as what happened in September (and on the exact same day!!) Could this just be because my period was supposed to come on the 17th last month, and is getting back to its new normal, or should I be worried that it's something worse?? I did have quite a bit of extra stress within the last couple of weeks, so I guess it could be that, but it still worries me nonetheless that it could just keep happening. I'm 19 and have had no other symptoms of anything else, and no sexual activity.
