Acupuncture may have messed up my cycle?

Sarah
I have tried acupuncture this month and am worried that it has messed up my cycle. I am usually pretty predictable and have a long cycle with a luteal phase of 13 days, and EWCM on one fertile day around day 18. This cycle with acupuncture, I had no EWCM and a luteal phase of 10 days. Has anyone had a similar situation or any thoughts/advice?
