Problems after depo

Lynzee • Mommy to Ammarie, born on March 3,2016!
I only took two of the depo shots before I realized how crazy it made me. My last dosage was October. Well, I had my first period in April, and have been trying to conceive ever since. 
This week I had my period, thought I was done because I didn't bleed for a day, then I bled the next day. 
I just want two days with nothing so I thought for are I was off, but I started spotting  this morning. 
Idk what to do. I'm not sure if I'm on or off and this makes ttc so hard!
