Ya so ever since my period had been constant I could literally tell someone the second it would be coming. It was on a beautiful schedule that worked well and I liked. Now last week it didn't come, and didn't come, and didn't come I was like honestly what the heck this is so not like it, wayyyy offfff schedule. I was kinds wondering. So I looked on the internet and stuff and didn't really find anything. And I knew 89% percent that I wasn't pregnant.. Lol. So then finally 4 days later it came! I was so happpy. Cause I actually thought I was going to be way off track. But then it only lasted 2 or 3 days and always it's lasts 5 or 6, I could probably tell you the day it would end before it even started also, so that was confusing me too. What could be happening. I had sucha great schedule and thing going, now what? Why would it start to go this way?

Sometimes your body's schedule may just randomly shift. It could also be affected by your closeness with other women. Being in a workplace or having a roommate often can cause a cycle to shift because of pheromones. Often the cycles will synchronize.
