My period stopped for 6-7 months after i stopped taking the pill.
When you stop taking the pill, your body thinks you are "pregnant" in a way, and thus stops your period.
It takes a while for the body to figure out that it needs to restart generating some hormones that were in that pill.
Then again i was 22 when i stopped taking the pill.
I suggest you consult with a gynochologist, (the one who will not tell you that taking the pill will solve all your problems, because the pill itself is a source of many problems)
P.S.
After those 6 or 7 months ended, i had periods that lasted between 18-35 days.
Only after about a year of when i stopped taking the pill, my monthly cycle returned to normal.
So your period not being there, may just be a side effect of you not taking the pill anymore.
