I am 24 years old. I was on the depo shot for 7 years, my last one being on February 22, 2012. My periods became regular after about 8 months. About a year ago I began doing ovulation tests and also had his sperm tested(just a store bought test). Those read fine for both of us so I made a doctor's appointment. She put me on a birth control pill for 1 month. She said to take it every day at the same time and when finished it should reset my hormonal balance. That was just over 4 months ago now and still no luck. Need to make another appointment but I guess I'm just looking for a chin up!
