Please help!!!!!!

April

Ok So on December 6th I got one depo shot in my arm but the lady that did it she didn’t put all of it in my arm the right way so i was suppose to get another one in March and I didn’t want to cause I want to try for a 5th baby so my question is if I still had the depo in my system can I still ovulate or does it have to be out of your system for you to ovulate?? Cause I was ovulating
