Need answers please

I don't know where to post this exactly but my husband and I have been trying for #2 for 7 months and have had no luck. I read somewhere that the Depo shot causes temporary infertility. I only had 1 shot and that was well over a year ago. I read that from the last shot you got it can take up to 22 months to conceive. Have y'all gotten the shot and once gotten off take less than 22 months to have a baby??? We are worried and if we cant conceive naturally then we will consider IVF or IUI
