Counts will fluctuate, but your counts are trending down, and that's what they look at. It took me a year to go from 800s to 500s, and there were fluctuations like yours. The second year, three extra caps/week were added, and I have stayed almost consistently in the 400s for five years.

Call the doc if you are worried, but 689 to 700 is only about a 10-point rise. Mine fluctuate regularly between 425 and 525.

It's nerve racking, I know. Hang in there.
