14 Day Cycle - any thoughts?

Dee • 42, happy mother of a lovely boy through ICSI on 3rd round. TTC #2 since June 17
I usually have a 21-24 day cycle which is ok but ideally I would love it to last a bit longer. This months I guess my hormones where turned upside down cause my cycle lasted only 14 (!!!) days. 
​Has anyone experienced it before? Anyone any thoughts?
