Cycle experts - what does one very short cycle mean?

[WaterBelle]

Usually 26-28 days. Last month it was 22 days. TTC since November,so not that long but that was my shortest cycle ever so confounded me a bit.
Is it an annovulatory cycle?
Haven't been sick, in a plane, suffering stress or anything like that to explain it.

I'm currently on day 25 of next cycle so it was a once off. I'd like to try working out when I ovulate but I haven't got a clue.

Hi there I have had 3 x short cycle (18-19 days)in last year - all at times that I was quite stressed. I was really upset about it but I am trying to remind myself that even if they were annovulatory the other ones were regular so hopefully I'm still producing good eggs some of the time!
