I forgot to mention........

Hi,

I forgot to mention tuesday of last week I started my period. Thursday it stopped then started up again sunday. It lasted until wedsenday and now it's thursday andd it's just very slight and pink. I noticed the crashing fatigue on this past wedensday so my question is, could the fatigue be from this irregularity in this last period or stress? This has never happened to me before. I have always had a four day period. I do have a 21 day or so irregular cycle for the last I'd say 8 years. Boy, I am a hormonal wreck!!!!!
