When will it come subsidise?

I just started my spell on last Sunday. I have it VERY light Yesterday and sturdy the other 2 days. I have zilch Today.
So when will it come back? if you've merely started your periods they will be irregular for a few years, so it may come spinal column next month or I don`t know in three months time theres no track of knowing. After a while though it will come every month. hope this helps xx
