Hi dear, I have gone through your question and understand your concerns.
is medroxyprogesterone acetate
which has the common side effect of irregular spotting, prolonged amenorrhea
and irregular periods
The periods usually normalize once you stop taking depo shots.
There is nothing to worry, however you can stop taking further depo shots if you find irregular bleeding troublesome.
Hope you found the answer helpful.
