Depo shot

Morgan • Finally have my rainbow baby!❤️
I was on depo for 3 years, and have been off of it for almost 2 years (will be 2 years in January). Hubby and I have been trying for those almost 2 years. Had a mc in December, and nothing since? I have regular periods, and ovulate monthly. I don't drink often, and trying to stop smoking. I have been smoking around 3 cigarettes a day now. I eat healthy, all the time. Someone please help. 
Drs said that my mc was Normal bc of how long I was on the shot.
