Cycle has gone from 72 days to 38! Is this good?

[Chrissi]

Hi,
Over the last year i've had a range of cycle lengths. Sep - Dec 2012 they were 14 days. Jan- Aug 2013 60-70 day and this cycle was 38 days! Does this mean my body is finally clearing out all the hormones etc I've been pumping into myself?

Thanks in Advance,

Chrissi x
