Grrr! What the heck?

Ever since I've had my first time at 13, they've been completely regular. Like I can set my view to them! even after having 2 kids, it go back to middle-of-the-road. I'm 27 now, so thats 14 years of common, regular periods.
And today ... BOOM, I carry my period 2 weeks untimely! just out of nowhere!
Why did that come about =( .. ? There could be several reasons. A lot of times after a pregnancy you are gone with a different cycle. I wonder, be your last length a normal interval? Was it lighter than normal, last less days, anything unusual roughly speaking? Because could be that it was something more similar to spotting and this one is the real spell coming late. But.. stress can do this, it's possible you have a miscarriage. You say you haven't lost/gained immensity so that's not it. This really isn't something to worry roughly speaking as this happens to almost everyone (I know, I know, it's not typical for you) -Unless - it happens again. If your cycle go back to regular after this I would a short time ago brush it off and consider it stress. If however, your cycle continues to be irregular next it needs to be mentioned to your doctor as nearby are a multitude of things (pretty much all hormonal, adjectives relatively common, and sort of easily treatable) that could be cause this. I know it's really strange to be clockwork and then enjoy an off one, but it really isn't anything to verbs about. It's so adjectives.
umm cause ur cycle changed...it happen or ur expecting
