I have seen your question,
Depo Or commonly called Depo-provera
Injection is an effective contraceptive
, it is generally taken every 3months , but it does have few disadvantages, after discontinuing the dose periods return slowly , some people may become pregnant within a year or two years.
Hence i recommend you to wait for 6 months and i assure that you will become pregnant for sure but it will take time.
For any further guidance i recommend you to consult nearest gynecologist .
I hope this helps you ,
