ANY ADVICE WELCOME- How long will it take??😞

Allison • Married💍 Mama of 3💙💙💖
Just out of curiosity how many people have experience with the Depo shot? I was on it last year (2016) from about February/March and had my last shot in August.. my husband and I decided we wanted to try for a baby in August but before I could talk to my dr the nurse gave me the shot 🙄 So now I feel as if I'm in limbo until my period gets back to normal which according to other sites can take up to a YEAR!
 I had what I think was a period November 23-26th but totally missed a period for the month of December... thought I might be pregnant cause I've almost felt like I had the flu but took multiple tests and all were negative. 
***Any advice???
