[missy87x]

I always get my period every month it's sometimes on the day it's due or a few days early or a few days late never 9days late like it is right now. Done 4 pregnancy tests and all negative. Anyone had this before? Iv been to the docs and they were at all concerned since I done tests and where all negative. Is this normal I'm worried there's something is wrong with me.

Please try not to worry. There can be many reasons why your cycle can go amiss and very few reasons are sinister. Most women have this happen and you may never know why. As long as your not in pain I wouldn't worry.
