My period is pretty regular. I use an app to track it and it's reasonably accurate, usually within a day. So I was quite surprised when my period started yesterday, 5 days early. It's very definitely a period. What's more interesting is that my PMS symptoms just started Tuesday. So I'm getting all of it all at once. So, my question is (knowing ymmv and all that), how early would my period have to be for me to be concerned? I'm not concerned really, just curious more than anything.
Possible contributing factors – (just one, really) FedEx lost my brand new $900 laptop and I have been extremely stressed about this all week. And really quite enraged to the point that, despite being EXHAUSTED, could not sleep. I imagine that this is probably related, but doesn't stress usually delay your period?
