Acupuncture and period, do I have to keep up with acu

KeraT

I have been missing every 3rd period all of 2018, ever since my miscarriage end of 2017. I have also been skipping December period for past 4 years. I started acupuncture in December & after 2 sessions I surprisingly got my period in December after 4 years.

Very happy with life l, thinking I am cure, I eagerly waited for my period or bfp in January but no period and no pregnancy at 3 day late period. I wonder if I need to keep up with acupuncture to get my period now. What happened to my cycle
