Hiya Ganiggle. Some people ovulate as early as cd8... but your symptoms could also be a sign of ovulation. People have different ways of telling if they have ovulated or when they ovulate... through a fertility monitor, temping, checking CM or CP... and all work differently for different people.
I have ovulated in the past on cd13... and when I ovulate I get very tired, so it could be a sign of ovulation, but it could also be pregnancy. Here is a link to a useful website...
